These tuner for a multiband antenna was design by Frank Lamprecht, DL7AQT, and published 2002 in the QRP-Report. We want to set up SKY COMMAND to a remote-base HF station at the Naval Academy over on the Greenbury Point antenna site that members of our club can use as shown below. I would think that the 5/8 radiator may have slight gain advantage, but believe that the J pole may have a slightly lower angle of radiation. Antennas are either monopole. Add each section as needed to reach desired height. It is extremely important to tune the ham sticks as a pair in the dipole configuration with an antenna analyzer. Basics The antenna consists of a vertical half-wave dipole that has been folded virtu-The “C Pole”— A Ground Independent Vertical Antenna KF2YN takes the vertical to new heights with this folded design that doesn’t require a counterpoise.

Figure 3: Two-element Yagi and general Yagi geometry. The finished antenna on a rotating. 20m antenna is simple and cheap to make, and has a performance that matches commercial antennas but at cost considerably lower. 8 x lambda/4. For the antenna and feed, one option is to use a 50' role of small speaker wire (I use 24AWG from Radio Shack) or 2-conductor computer cable. It has gain and wave angle comparable to a full-sized ¼λ ground plane antenna with radials. There's been a lot of discussion lately on the Yahoo Groups ndblist regarding the "low-noise vertical" (LNV) and it's seemingly excellent performance. To disguise your antenna, you simply surround the bottom of the crappie pole with an old fishing tackle box, portable cooler and fishing net to provide your new stealth antenna with maximized visual effect.
