I am a 74 year old “newbie” I just earned my technician’s license 3/24/21. I LOVE your videos Dave. Not only do they teach me what I need to know, I have to learn a whole new language just to glean the the tremendous information you impart.

You have taught me more about antennas in a day than I have learnt in 20 years

My DX Commander with 30 radials of 2.5m and 19.5m of wire as an inverted L has a sweep of SWR < 1.5 from 3.6MHz to 3.85MHz. It is a truly broadband antenna.

Awesome Dave, you answered a lot of questions on the subject .Great videos Dave cheers

What a great presentation on 80 meter dipoles. Thanks!

Very Helpful information. Thank you Dave!

I've been trying to build an antenna for 75 meters and I'm telling you it is tough! So I really needed to view this video again.

Great explanation on 80m. Very true about tuning a vertical antenna to the band width one wants to use. One day I’ll get it-one day.

Great explanation, thank you!

Just make a doublet. Follow Dave's advice about the angle and wood. Cut insulated wire slightly longer than normal resonance at the lowest part of the band. Feed in the center with ladder line. Just before that enters your home install a balun. Run off that with a short pice of good coax into the house to a normal external tuner. Will tune all bands 80-10. That was my first antenna over 30 years ago and it was great. In the years I was active I made 100s of contacts on all bands except 15. For what ever reason it would tune up but had awful performance on 15m. Keep in mind I was 13 when i put this up and had no one to help me so construction and installation was shoddy Like Dave's suggestion of the loop. I am putting one up myself cut for 160. If you make it square keep in mind each side is only 1/4 the length of a normal dipole for the lowest band you want to work and will work for the lowest band through 10 meters. You will need a tuner and feed it with.ladder line through a balun like the doublet.

Dave... Very good explanation. I’ve heard about many of the things you mentioned but you bring it all together and tied the ribbons on it. Many thanks.. de... KE0EF. Fred

Good video, I need to watch it again and take some notes.

Here is what I found on the 75 / 80 meter band antenna situation. A full wave loop is one of the better choices if you have the room. I have one and it ranks as a great antenna. I also made an off center fed 75 meter dipole antenna that has an SWR of less than 1.5 from 3.700 to 3.999. Using #10 gage stranded wire really makes the antenna very broad banded. I also use a DX Engineering 4:1 balun. Being fed off center, it does work pretty good on 40 meters and 20 meters. I do use a tuner (Dentron MT2000A) on 40, 20, 17, 15, 12 and 10 and it all works well. I'm up about 70 feet in a tree. Wire thickness is often ignored by many and that I believe is a mistake. I used to use 14 gage wire thinking that it really did not matter.....after using 10 gage wire, I found it really does make for a way better antenna. Don't cheap out on wire. And if using a balun, get a high quality one not the ones sold on E-bay or Amazon for around $20.

Great lesson!

Great video, dead on (and I didn't fall off my tower lol) Just put an old G5RV today for 75. Have issues with my MFJ-1785 rotatable di-pole. I read the instructions after I tuned it near the ground and didn't add the 500kc that it shifted when raised. You're right on and I understand the other guy. My mid point is at the top of my tower (43 feet), raised by dac cord and a pulley I installed. At 2.5mhz swr is 1.3, 3.1mhz =4:1 & 4.0mhz it's 9:1 (via my Nano VNA, best tool I ever bought) From 2.4mhz to 2.75mhz the swr is 1.8:1 350kc, with a dip in the middle. I got lucky my LDG tuner can handle it. I called for a signal report 3.966 and had a couple of guy sayI was booming in Ohio. I'm in northern Indiana and made a 5-9 contact to Kentucky tonight. Very informative video and it all made sense. I know what to fine tune. I spaced my ladder line away from the tower with a couple of 5ft fiberglass rod driveway markers you see at the hardware store so you can find it in the snow.

80 meter antennas are something of the deep subject! Good stuff, but something to look into for sure. Thank you Dave! 73 de N2NLQ

Thanks Dave, you're a damn good teacher!

question. what if you have a full 160 loop ? what would that do to tuning 80 m?

Would adding capacitive loading at the ends of the radiating elements open up the Q and make it more broadbanded?

My mobile 80 meter antenna is very narrow banded! Like mentioned in the video I have it tuned for the center frequency between the two nets I frequent. With the internal tuner I might get about 40 khz of movement around the band.

On a dipole or inverted V why use balanced feedline into a balun instead of simply running the center of the 50 ohm coax to end end and the shield to type other end and then sealing it off?

When I was in the UKI couldn't put up HF antennas, except for a 20 metre dipole under the gutter, fine except when it rained. Only had it a few months before I came to Portugal. At last I'm starting to get set up here. I'm watching all your videos for hf advice.

Nice to see an older FT-101 in your collection,That was my first 101!

I have the MfJ 10-80 ha!f wave end fed. My MfJ 998 tuner can tune it to about 1.1 to 1.3.. at 3.800. At 3.963 where my net runs the tuner can do no better than 1.5 to 1.8. If I shorten the antenna to bring the swr down on 3.963 am I right that the swr will be lower on the 40 & 20 meter band higher up on both bands than it is now? I could live with that if I could get a lower swr on 3.963.

when u run a wire for a dipole should it be stranded or a solid wire?:??

I recently got a Tune-A-Tenna, which allows me to change the length of the inverted vee from inside the shack. I still need to work on positioning things to get more apex height, better orientation, and less interference/coupling problems... but it’s looking very promising for allowing me to get it resonant anywhere in 75-80m that I want to operate. I’ll keep you apprised of my progress. Should be very interesting.

Good discussion, and timely for me. I am assembling a 135 foot inverted V Doublet to deploy on my trailer mounted tip up, jack up, mast, with 45 feet of elevation. It will be used with a manual Palomar 200W tuner, and my Icom 7100. 80M is a definite main target of this system. I am also building a Vertical loop on my city lot, but that project is a couple months off, it will not be at ideal height, but fits my property where a horizontal loop will not. WS7PB

I have seen wire antennas that are 3 wires with something spacing the 3 wires apart. Is that to give it a wider bandwidth? Or is it for something elce? If it is for bandwidth how much will it help and how far apart should the wires be. I didn't get a good look at it but I think they were around 4 to 6 inches apart. I may be way off on the spacing apart. What would be the best spacing? I had been thinking about using 450 ohm window line for the long wires. I think that may give a wider bandwidth. But then I may just have it all wrong.

Great video David... I have a Fritzel FD-4 OCFD only about 24' off the ground at the moment. At 3.5mhz I have 4.9 swr at 4.0mhz it is at 3 swr. I am going to get a telescoping fiberglass pole to raise the feed point up over 40' and hopefully lower the swr on 80m and 160m. Other than 160m and 80m a built in tuner will allow you to work all the way to 10m. My first "real" antenna but so far so good. But what do I know I did not stay at a Holiday Inn last night.....

Hi Dave. I wonder if he has loaded the antenna with his rig and its swr meter or an external swr meter and if so what did it read as the swr? Since he said he used an antenna analyzer for his measurements this may be what is going on. If he lives near to an AM broadcast station its RF may be picked up by the very low power analyzer with a very sensitive swr meter and the incoming RF makes the instrument look like it's seeing a high swr. I live a mile from KGRE 1450 and using an MFJ antenna analyzer I saw 2.5 to 1 at its lowest point but flat using the rig and a Drake W-4. While looking at the MFJ's meter I saw the meter fluctuating minutely with their music and deduced what was going on. As I went to 40m it was much less and 20m flat with the respective antennas. KGRE is 1KW omni 24/7 with a 343 ft tower with 120 400 ft radials. I hope with the rig and a regular swr meter he saw a good match. My antenna is an 80/40 inverted vee and 20/15/10m a 4 el beam.

Dave, the answer is under the snow in your backyard. The DX Commander actually does pretty well on 80m (a slice anyways on the phone segment) if you set it up as an inverted L as Callum describes in his "instructions" and videos. Mine is 1.40 near the center of the phone band (the General Part) and is never higher than 4.5 SWR anywhere and usable with a tuner. Obviously, he'd need some radials but the thing is really easy for one person to handle. Way easier than climbing a tower. NK5J.

Agreed. I have a homemade vertical with not nearly enough radials, and with an old icon AT-500 tuner I can work the entire band. I’m sure I am not doing as well as I would with other antennas, but I am getting out and having fun, which is really what matters. OP, Don’t give up. I would try the ladder line and a 4:1 balun (which would make it a doublet) then you also can tune it for use in most (if not all) higher HF frequencies.

The spreader material I'm not sure of. All the antennas made with these materials last many years. My 12.4m DXC has already been through multiple tropical storms, ice rain storms, mini flooding, and hot weather so far. It isn't even a year old yet! So far, other than falling over because the front-end loader doing snow removal snapped the guy peg, it has shrugged it all off. (No damage from the fall that I could find, and that was in winter, so around freezing.) I guess we will see how it lasts.

Can I make a Fan Dipole antenna for 2 or 3 parts of the 80 M to have something that will cover more of the band. I have a 58 foot tower and can use top rail to get the end up 20 feet. I was thinking of one in the digital part, another in the middle and the third near the top end. I know the thicker wire will make it more broadband. Thinking about 3 sets of 12 gage wire.

Question, there are "Fan" dipoles right, so would a fan dipole with 3-4 wires cut to different 80m trequencies work? The multi band fan dipole picks the right wire for the frequency desired, would it do the same within the same within a particular band? Just a thought.

i'm going to get away from inverted vee' just for a moment i have to eighty meeter ham sticks and a mounting brackets ? will cover all of eighty meeter band

I got a 10 foot 1.5 inch PVC. That gives me 2 ends that are 4.5 feet from the tower. Put I polt at each end with a pulley at the ends so I can lower it to make repairs.

There is an antenna that will cover all of 80m, well 160-10 really. It's a compromise antenna. The Icom AH-710 folded dipole at 80ft. long. (doesn't preform well at 160 though it matches within 3:1) :D

I’m in the minority as my 80m single band center fed dipole covers over 300kHz with a 3.0 or better SWR and over 200kHz with a 2.0 or better Swr. In other words from 3.650 to 3.950 with a 3.0 SWR or better. Or 3.700 to 3.900 2.0 SWR or better. And I’ve used this antenna at different heights and different configurations and the results were always the same.

I use a doublet antenna with 58 feet of wire on each leg fed with 450 ohm window line. I have a 4:1 balun hooked to the window line and rg 213 going to the tuner. I can use it on every part of 75 and 80 meters on down to 6. It will not tune on 160. The only drawback is that you have to have it high above ground for good performance. Mine is 70 feet on one end sloping down to 30 on the other. I use a pulley to raise it up and down the tower.

Overall a good video. To get the feedpoint impedance from 20 ohms or 30 or 40 to 50 ohms use a match. I only use the hairpin method. It goes by other names as well. It is easy, effective easy to adjust and cheap with the advantage that its value does not change ever and both legs are connected together to make a DC conection. It get rid of a lot of static. Read Beam antenna handbook. It explain it the best. And off course a balun. I prefer a air wound one. 1:1 ZS6ABR

Need to look at at DX COMMANDER all band vertical

The full wave loop fed with window line is your best bet,.

I've run an 80M dipole for many years with a 1/1 baking at the feedpoint. Feedpoint is at about 25', ends at about 10'. Never has an issue getting a good swr and bandwidth. Excellent NVIS performance. I now use an full size folded Dipole with a 4/1 baking at the feedpoint. Again, no issue getting good swr and bandwidth. Slightly broader than the dipole. Also a bit quieter. Seems like he has something else going on.

@ve3pcp

Balun, not baking.

Not mentioned here are some of the practical issues. Check the feed line for DC continuity and shorting with a multimeter. Check the feed line with RF into a dummy load at far end. Can the instrumentation be trusted and verified? Cross test the analyser with a conventional VSWR bridge to a known good antenna for example. What material is the radiating elements made from? Wires with a high DC resistivity like various steels a will not tune unless quite thick. Insulated wire will resonate at a shorter length than bare copper. Try to conduct testing and tuning close to the feed point using a minimal length feed line.

why not a non inverted v?

A 274 feet (or 83,0m) loopantenna You c a n use at abt 10feet (3.0m) high then it is a s c NVIS antenna. Feed with 76 feet (23m) 450Ohm windowline and DC Earth on opposite side of the loop! It requires a 2:1 or a 4:1 balun (f ex MFJ969/962)

Im an Oggy and im in eastern Europe.

I'm discovering just what you describe about 75/80m. I found the 12.4m wire vertical too noisy on 80m, so I also have a 131 issue foot efhw in an L due to lot issues. Much better RX on the efhw, better TX on the vertical. I have been considering a low full wavelength loop. Higher bands are a very different experience.

My MFJ-259B says that my home brew OCF dipole has SWR from 1.5 to 1.8 from 3.5 to 4.0 MHz without a tuner. Is that possible or is something wrong with the analyzer?

@davecasler

3 жыл бұрын

It is possible you may have a lossy feedline or balun or something. Losses can masquerade as low SWR.

I believe you can make a dipole covering the entire 80-meter band if you build it with three parallel wires instead of one. One wire is cut to the lower end of the band, one for the center, and one for the upper end. The three wires all run parallel, held about two inches apart by insulators. Another possibility is a "cage dipole" which consists of 6 or 8 parallel wires held apart by insulating rings to make the antenna appear at radio frequencies to be electrically larger in diameter.

SWR 9.9 in the case of your analyzer means that it is beyond the measuring range. Your antenna's feed point impedance must be either below 5 Ohms or above 500 Ohms. That should not be the case even when a (resonant) dipole is much lower over ground. My first guess would be that the center of your dipole is too close to the (probably conductive) tower. If this is the case, feedpoint impedance can go wild, because you send almost all radiated energy of your dipole into the tower instead of the air. If you can elevate the feedpoint about 2 meters over the tower with a non conductive pole or apply a rope to get it farther away from the tower sideways, try that. But before you do that, check the antenna system (antenna+feedline) for simple electrical errors. Take the balun out of the system an connect the dipole directly to the feedline. Measure the feedline for internal short (inner/outer must be open). If ok, measure the inner and outer conductor of the feedline against the corresponding ends of the dipole.(one short per side, no more, no less) If you want more tips on how to go on with a differential diagnosis of your problem, just comment back. 73

K6SDW: The MFJ-17758 80/40 meter trap dipole was, for me, the perfect solution for an 80 and 40 meter antenna. With the trap inductance the antenna only needs about 85 feet to cover both CW bands. I worked the world on CW/FT8 with this antenna. I would also suggest a 9:1 balun endfed antenna, which I've used as well, again on 80 meters I've worked the other side of the "flat" earth running FT8.....I couldn't resist the "flat" earth comment, what a joke!! 73/ed

G5RV is an obsolete antenna. It was a compromise in its day. The ZS6BKW version is much better but still a compromise.

John , I’ll save you 23 minutes of confusion. Buy or build a 80m double bazooka. It will be under a 2:1 from 3.6-4.0. It was made to throw on metal and not throw off the swr.

If my radio had an internal tuner I could have stuck with that, but not having a tuner at all forced me to add the other element. I used 10 gauge wire and that gives me far more bandwidth than the usual 14 gauge that is used. My voice element is about 59’ per leg and the cw element is at about 65’ per leg. The two elements are spaced apart 13” from each other and it is currently a sloper that is only about 15’ off the ground on the high end.

Getting a nanoVNA to perform as an SWR meter takes you a couple levels down into the menu. I almost did a video about it, but then "they" changed the nanoVNA menu!

I use a Double Bazooka works great wide band dipole configuration. I heard inverted v works better.

HA! HA! You pulled a "BIDEN" at the end!

thanks Dave, this helps a great deal. KB1GYS

A G5RV with an ICOM AH-4 tuner works reasonably well
