I love your AB testing with wspr. I do wish it was easier to get a truly scientific measurement of antenna performance but you never know if the ionosphere gods just decided to crank the knobs up to 11 for the ATAS or not, lol. Still it’s the best we hams got and I think you’ve helped me make an expensive decision slightly less expensive ;)

Thanks Sterling. WSPR is about the only way to remove all human influence from these kinds of tests. On air just wouldn't do it because signal reports are so subjective. I like to use WSPR because there is undisputed data we can gather while eliminating as many variables as possible. Propagation is always going to be the wrench in that equation, but if we get a big enough data pool, we can start to see certain trends. I was out 3 consecutive days doing this and gathering information. I made a couple mistakes the first couple days and threw out those results, but I can say without a shadow of doubt, even if I put in that data, it would only further support the ATAS, and the gap would only grow farther between the two. Every single time the ATAS was on the air, it both heard and was heard by more stations.

At last, a credible and unbiased comparison of the ATAS vs XXX antenna.👍I've used one for several years and the only problem I've had was last year when the motor gave up which, in fact, turned out to be the small drive PCB in the base which I changed out. Still not really sure why that gave out. The BIG plus of the ATAS is undoubtedly it's auto tuning function with certain Yaesu radios which is a huge advantage when band swapping. It does require periodic maintenance, especially if used in wet weather and IMO is NOT fully waterproof straight out of the box and some careful use of silicon grease can save expensive problems later. Look after it and it will serve you well for years!👍

I started out with the ATAS-120 with my FT-857, both of which I bought new at the same time. I started having problems with the ATAS-120 after about a year, where I had to take it apart and repair it. About six months later, I couldn't repair it. That would be about 2010. I stopped in an HRO and bought the Little TarHeel antenna, and it's still working now. Just holding the two antennas at the same time you can feel the weight difference, looking at them you can see that the TarHeel is a much more robust antenna. I didn't run tests or anything like that, I just used the ATAS-120 until it failed, and it failed far too soon. To be perfectly honest, I would not own another ATAS-120 antenna, which is why I assume they are readily available. I think the TarHeel is superior by comparison. You may like the ATAS-120, and it may work for you, but when it fails, and I'm sure it will, go buy the TarHeel and you'll never look back. A year and a half versus 12 years while still going strong. I don't think there's any comparison. I wouldn't take another ATAS-120 if it was given to me, I'd suggest they offer it to someone who might appreciate it, and I don't fit that bill. Just my honest opinion. I have absolutely no respect for the ATAS-120 and consider it a costly mistake. Live and learn.

As far as my station goes, the ATAS-120A is the best for me. 8717 mile contact from SW Florida to Northern Cape Province South Africa with 50 watts on my FT-891. Not too shabby. It is the perfect match for ATAS compatible radios on the go. I'm hitting Spain with a good signal strength on cw and 35 watts. Like you... I am finding this antenna a pretty good piece of kit. I am very pleased with it.

Great content Mike. Been running the Atas on both my trucks for 3 years for chasing DX and some local rag chew. It is definitely easy button with the 891. Yes, some folks have grounding issues, some don't like yourself. Slapping it up works, and spending time nitpicking will also pay dividends. Tinkering with bonds. grounds, choking etc., can help with better tuning characteristics, signal reports and distance. Both of my vehicles were different installs, with different challenges, and perform noticeably different with the same setup, and that includes takeoff angle, which is cool. But both perform amazingly. Such a good little unit. Thanks for the hard work Mike. 73 AD6DB

Years ago, an Aussie ham rigged up a coil to put the ATAS-120 on to 80m.

Surprising results, I was not expecting that. Im just installing an atas with a home made controller so I can use it with any rig I want. Can’t wait to have a play. For half the cost it seems a good buy.

Interesting result, thanks for the effort. One way to use WSPR data is to use only those reports from stations that heard both antennas, and compare the signal strength values. Would be interesting to see comparisons to Hamstick style antennas and to the HiQ and Scorpion as well as the larger TarHeels and perhaps the Hustler resonators as well as the popular Icom AH-4 or SGC tuners into a whip.

Tnx again! Great info.

I run an old atas 100 and an 857d mobile and love it. It’s a simple easy slick set up and I get good signal reports mobile.

Nice comparison Mike. I concur! I have owned both of those and use to run the ATAS - 100 (120) on my F-150 with an FT-100 or FT-857 and had great results (Finland from California). I ran the TarHeel with my IC -7100 on my Volt with less success. I still have the two antennas and the FT-100 and IC-7100, but they are not used mobile anymore, just on POTA or at the ham shack.

Thanks for collecting data to analyze. I appreciate that effort. "Blowing the doors off" is a little strong of an evaluation.

I use an original DK3 Screwdriver antenna that was designed by the father of screwdriver antennas, Don Johnson - W6AAQ (SK). The antenna has a very high "Q" and is motorized and tuned via a on-off-on toggle switch, while listening for the highest band noise. Once you have high band noise, a quick look to verify the swr at the radio is acceptable, and you are ready to go. I have been using this antenna since 2005. This antenna started the screwdriver antenna genre. It still works great! 73s - DE AG4KN - John

I have the 891 and ATAS 120A combo. Works great for the most part. On 40 I have a problem with flutter, for lack of a better word, that is obviously associated with vehicle motion. Some connection is intermittent when the antenna is extended long enough for 40m. It doesn’t happen on the other bands. It is the antenna because I have two mounts on the truck and switching the antenna between them does not resolve the issue. It’s not a super big deal since I usually drive during the day when 40m is not all that great anyway. It affects both receive and transmit, as you might expect.

Love mine with the 891

Very cool analysis I have done similar comparisons with several antennas I've been operating mobile since 1975. The ATAS 100 That I currently use is not better than any of my previous antennas a matter of fact they actually perform less however it is so convenient that I can wind it down pop it in the trunk when I'm not using it. A lot of people don't realize location is very important when mounting in antenna a bug catcher antenna which is extremely efficient when mounted on the rear trailer hitch is the worst place for it. We are as a smaller antenna up near the cab of a truck would work better. I used to run the high power hustler coils to change bands I would pull over fold over the mask change the resonatorAnd then continue I ran a full 1.5 kw killowatt in that mobile. That was my most outstanding set up. I remember running HF packet while my girlfriend would be driving. Today's cars are not very esthetically pleasing with a giant Bug catcher or even hustler coil on them. The atas Still is a bit obtrusive but better than most.

I recently changed from using ham sticks to the ATAS, so far I seem to be getting about the same results but I was able to remove the auto-tuner I kept in-line with the ham sticks and I love not having to swap antenna's any more.

Hi, i am using a ATAS because i purchased it cheap with a blown Motor driverboard, fixed it, used it and was a littlebit disapointed with the performance on 40m, so i drilled out the head of the coil and mounted the whip from a smashed Wilson 1000. I worked VE7 from the Rhine-Main Area in Germany. 73 DH9MM

Great review! Yaesu should make a mobile radio that does 40m-70cm, just like the ATAS. And it should have a detachable head that the mic, USB (for digital), programming cable and external speaker plugs into--that way the body could easily be mounted in the trunk/back of the vehicle. I'm sure I'm asking for too much.

Thanks for your exhaustive tests Mike. While they do give a good indication, they are not 100 % conclusive. For them to be conclusive, the tests need to be run simultaneously, at the exact same time. Too many variables - changes in band conditions.....stations going QRT in the next session before changing antennas....stations moving their beam headings before you swop over etc. But it was a thorough test, well done. Since I have owned my Little Tarheel II for more than 15 years, and I have owned ATAS100 and then 2 x ATAS 120 for 20 years...I would, in my experience, give the edge to Tarheel in terms of performance, However, for the convenience factor the ATAS is far more convenient....when using a compatible Yaesu rig.

I recently acquired an FT891 and ATAS antenna in a trade deal. It has been working out great and I have knocked out quite a few mobile POTA contacts as a hunter.

Surprising numbers. Would probably be very significant for digital modes, but I wonder how well they translate in to hearability for SSB? Not sure there's any objective way to measure that. I know the audio on all of my radios is much superior to my diminished hearing after decades of .mil aircraft and shooting ranges. I've had my Little Tarheel II for over 10 years and other than having to replace the coax assembly and mount due to years winter road corrosion, no issues. It keeps on going. However, a couple of folks that got the ATAS at about the same time have long since discarded their antennas and gone to something else due to issues that cropped up over time as they apparently did not hold up. Anecdote is not data, and maybe they got their antennas from a bad batch. Who knows? Certainly not trading my Tarheel in anytime soon Good test and good video. 73 KAØAZS

Mike I use a Little Tarheel II with my 857D in my F250 pick up. I have all doors, hood, tailgate and muffler grounded with 1 inch braid works excellent I have had no problems with this set up. Did you bond you car to the frame or how did you ground everything.

Im trying to figure out the best setup for my f250. How did you mount your ATAS, and how did you mount your 857 in the truck?

I use LT with my IC7000 and an original ATAS 100 with my FT-100D which does all bands.

Will the ATLAS tune gmrs frequencies? I understand its not stated in spec but will it?

No just trusty ole Huntsville.

Maybe you could use the Skyhook, which I got by-the-way, to put an ATAS well guyed and clamped up on a military segmented mast, up at 20+ feet, with elevated guy-style radials to put this beast up higher. (I think you and be Callum are inspiring a new idea in my head to combine recent themes in your videos. I’d call it the SkyHook Skylab ATAS). It might be a killer performer.

I might be trying it elevated at my club’s next “Radio in the park”. Another guy in the club tried the ATAS with a tripod and ground radial field and a FT-857 last month. The ATAS-120 has been a good piece of kit, I just need to find the right extended whip. Thanks for the Tarheel comparison. At least I know my money was well spent. (I have an 891 and a 991a. Double duty helps too ). I’ll check out the last Mailbag Monday.

i have a atas 120 antenna. it is AWESOME !!!!!!! when it works .........started having trouble with it running but not moving ......the it would adjust up but would not stop and would jam at the top or would run down and not stop and would jam up at the bottom !!!! i would love to have another one but i never found anyone that could explain what was wrong. any help would be great. thanks

For those of us with non-Yaesu rigs the difference is not as clear cut since we would have to buy a controller from another manufacturer. Enough to change someone's mind about which to get? That's up to them.

"Passed with flying carpets"?!?!?!? Never heard that one before. Also would like to know if you used the same radio for both and what was it?

A Yaesu radio in a Ford *Fusion*. Perfection :)

FT991a works with ATAS 40M -70cm. All modes All Bands

Tarheels need to have a really good RF ground. I have used both the Tarheel model 100 and the little tarheel which is mounted on my old 2003 Toyota Tundra. I have everything bonded together. The hood is bonded to the body, the body is grounded to the frame. The tarheel mound is grounded to the body and the frame. The body of the radio is grounder to the body. I have 1 inch wide ground straps tying everything to vehicle ground. Once you do that then you will have a good working Tarheel. This is the recommendations for the founder of Tarheel himself. Those 4 little ground points on the mount you are using isn't enough.

You can use the ATAS-120A with any radio with a MFJ-1825 ATAS Controller. It is a Bias Tee that simulates the control voltages of an ATAS compatible radio on the inner conductor of the coax. With this said, keep in mind that the center conductor of the coax must NOT ever be at DC ground potential while operating the MFJ-1825. IF you are using a balun for common mode current suppression make sure there is no continuity to ground in the balun. Ferrite beads on the outside of the coax may be the better choice for CMC suppression in this case.

@lunatech9516

You can use a MFJ-1925I2 to control it also. I've got the ATAS 120A and have used that controller with my G90 before I got my FT-891 and it worked well. Granted you'll have to figure out how to get the best SWR match after or while you're moving the antenna. I could use the built in swr sweep in the G90 while moving the antenna and set it. I've also just moved the antenna till the receive was clear and then fine tuned it using the SWR meter on the radio. I checked with my RigExpert afterwards and was pretty close to best SWR. Ground it very well and use a GOOD mount (I went cheap to begin with and had get the Comet mount to tame the SWR). So far the furthest contact I've made is Malta (5053 miles) using my FT-891 and the ATAS 120A mobile.

I own 1x ATAS-100, and 2 x ATAS-120A...and also the Little Tarheel II. The Little Tarheel is extremely well built and I very seldom hear of a failure. The ATAS is a lot more fragile and needs to be gently treated (one of my ATAS-120 stopped working several years ago, which is why I bought a second one a few weeks ago). Put a longer whip on the Little Tarheel and you visibly see better signals. Now my wish - I don't like Yaesu mobile rigs....in fact the only reason I bought an FT891 was to use with my ATAS - the pair operate flawlessly together. How I wish Icom made an HF mobile antenna similar to the ATAS, but that would work automatically with my 7100, 7000 and 706MKIIG

ATAS is repairable if you are technically inclined and careful. There's a pretty good YT video on that.

So that means you need to run the Tarheel on RX and the ATAS on TX and use a dow key to common out the Tarheel on transmit. That dual screwdriver life lol 😁😁😁

Which band(s) were used on the test? It would be nice to have a 1/4 wave whip to compare it to, especially if you are testing while stationary..

I was on 20 meters. I would imagine a 1/4 wave would blow the pants off of either of these antennas. I do use a 17' whip (1/4 wave on 20) often when I operate with my friend. We have no problem getting out. In all honesty though, these tests are fun to do and I learn a lot from them, but in the real world, I have made thousands of contacts with the Tarheel. It's a fantastic antenna and I would still recommend one. I do want to test the Tarheel with different length whips though. That is a huge advantage it has over the ATAS. I usually use a 6' whip and rarely do I need to call CQ more than 2 or 3 times. Then it's just pileup city.

They're both excellent antennas. The ease of use of the ATAS with Yaesu radios makes it a no brainer for me. Tarheel needs a separate controller. In my opinion there isn't really a big difference between the two to make it worth buying the Tarheel. The only reason I have the ATAS is because I got it used from a friend and the price was too good to pass up.

I have both, the Tarheel on my truck and the Atas on my company van and I doubt your results. It’s very hard to compare antennas but I have better results with the Tarheel. Ok I’m using a longer whip on the Tarheel 😀 The Atas is great for simple installs with just one cable. The Targetuner works awesome for the Tarheel.

Doubt all you want, I don't care. Numbers don't lie. The longer whip on the tar heel is a nice touch though. I usually use a 6' whip from MFJ or the 17' 1979. That's a huge advantage the Tarheel has over the ATAS, but, the ease of use goes to the ATAS hands down. Oh, and performance 🤣. In real world use though, they are very much the same antenna.

I've gotten my predator 10k that's meant for 10m and 11m to tune on 20m with a longer whip.

if your rolling with a Yaesu the ATAS is a no banner its cheaper and simpler. a huge knock on it is the wip if they just drip 2/70 and make the wip longer it would be a bit more efficient

Biggest issue for me is that I own an Icom IC-7000. I hear it’s possible to use with ATAS, but I dunno how much I’ll spend on it trying.

Spend all the money! MFJ makes an adapter. mfjenterprises.com/products/mfj-1925?_pos=2&_sid=c8f80c1ac&_ss=r $120 for an up/down switch though. That's a tough call. Still cheaper than the Tarheel.

I know that a reputable UK dealer recommends that if it rains, you should dry one of these and bring it indoors near a radiator as it's a common cause of failure having water inside, unsurprisingly. I don't know what the situation is with the other one. My situation dictates that I want an antenna on with these capabilities, but in all weather and 24/7. It's useless to me if it's drying out indoors. I'm UK, it rains a lot, sometimes every day. I drive all day, every week day. That's my radio time. I can't believe they can sell an antenna at this price point, and it can't handle rain. It's a mobile antenna, it should be waterproof or at least resilient.

Hmm, that seems like an interesting bit of advice given that these are literally designed to spend their whole life outside. I'll tell you I have had zero problems with either antenna in the weather. I had the Tarheel on the car when I lived in Michigan and it got covered in ice quite regularly. It didn't even flinch. The ATAS is also very well sealed from the environment too. I would strongly disagree with his statement.

Tarheels are absolutely bulletproof all year 'round in the Northeast US based on 5 years of experience with the 40A-HP, 200A-HP, and Little Tarheel HP. They don't leak or deteriorate with time. Not affected by water, ice, snow, or anything else I've thrown at them, though in very heavy rain, when the matching coil gets wet it does affect tuning until the excess water runs off. For the front-mounted antenna on the brush bar, I keep a plastic cover over it to prevent water and ice buildup; you could also mount it in a plastic bottle if desired.
