More Gain, More Power - 2m S2S Madness

Ойын-сауық

The Arizona Summit-to-Summit 10 Point Madness event provides a great opportunity to push the limits of 2m simplex and see what's possible over long distances. Although I didn't set any new personal records on this trip, some great contacts were made and plenty of fun was had.
The yagi is a homebrew design made from U-channel aluminum, steel hardware, and arrow shaft elements. The matching network is made from parallel 1/4 wavelength sections of 75 ohm coax to transform the 28 ohm yagi impedance up to 50 ohms. Those coax sections are wound a few times through a toroid as a common mode choke.
The boom is about 8 ft in length when extended and folds down to 32 inches. total weight of the antenna is about 2 lbs, and the pool cleaning pole mast adds another 2 lb or so.

    Great video, Adam. At one point I thought you were going to pull a Honda generator out of the bottom of the pack! Love the 2M yagi, but watching the elements screw on has me pondering different ways to deploy (attach) the elements. When deploying my own portable 2 element 20 - 6 yagi, most of the time is spent screwing it all together. Maybe magnet attached elements that saddle the boom. Nice to see you back. 73.

If I see the propagation forecasts picking up enough for that to be a possibility, you can bet I will be on a local mountain top with my station giving it a try. Thanks again for the kind words, and good dx.

Will have ago at building one of these. I've been reading about them, about gamma and hairpin matches. I am not technically minded so I guess it will be trial and error with that part. I've seen people use a strip of wire across the two elements on a tape measure yagi. Should be on the build in the next month. Motters M7TRS 73 👍🏻

    They sell aluminum telescopic ladders that extend to 5.5 meters. Weight: 14kg but if you cut off only 1 mast will be probably less than 5Kg. On top of that, if you can stabilize it you can probably put anorther 2+ meter of support since the ladder is made to support 150Kg.. If you manage to keep it straight up. Probably doesn't matter that much for 2m but still..

    Not in the least. The license helps ensure parts of the bands are dedicated for our use and keeps users from causing problems for others. FCC enforcement (or lack thereof) shows that one could execute similar levels of communication without them even noticing, you just wouldn't have many others to talk to. The call sign is needed for the radio games I like to play. The only thing I would be embarrassed about is being so paranoid of the world around me that getting an amateur radio license sounds like a threat.
