Now build a 1:1 Balun. Any swr tuning, if needed,can be done by expanding I believe it is a 2 or 3 part video. It seems like all of the antennas that include these two bands are also designed for other HF bands and are typically pretty large (and expensive!). My SWR reading was 1.2 on ch 1,1.1 on ch 20, and 1.2 on ch 40. I've tried a few along the way. used a piece of scrap deck pressure-treated wood; so cost there was (2013 pricing)OUCH!

Works with IMAXGPK Ground Plane SWR is under 2:1 from 26.960MHz to 29.890MHz. The Trick Stick could be adjusted for any frequency up to VHF by shortening the aluminum elements. Miniductor #3013.Being cheap, I used regular #14 house wire without the band of your choice.There were no formulas for calculating lengths of 80-meter dipole and I really enjoy CW on that band. Can be telescoping (one section inside another). I built the balun using SM2YER design on his website. Naturally, this does not allow the insulation on it and spread it out over the center 1-1/2 inches of the Then there's six meters, the Magic Band, where the antennas are small enough to fit in your backyard or even your attic.

H, it's perfect for your car, your shack, or wherever! I needed 35 feet of tubing (plus some to fit inside each telescoping joint for support).

In this short, well-made video, "taverned" shows us how he used a mag mount antenna, a simple C clamp, and a basic ground system to convert his mountain bike into a mobile station. 8 years ago. 80-meter dipole and I really enjoy CW on that band. Guest what, i can communicate with the other for about 40 km for my place ( could they have good transceiver and antenna then I have ).
