Subject: Distributed Capacity Twisted Loop Antenna
To: ham-ant@ucsd.edu
Has anyone used a Distributed Capacity Twisted Loop Antenna? The plans
for this antenna appeared in the July issue of CQ Magazine. The antenna
is made of twinlead, with a twist in it, and a hairpin match at the
feedpoint. These antennas are small, for limited space use, and can be
made for any band(even 160 meters). I have tried these and haven't been
having much luck. Has anyone else tried to build these antennas? I've
tried mine on 40 and 17 meters, and had no luck. What kind of experience
have others had? Let me know please.

Cut it in half and feed it half way up, like a dipole.

Would be kinda difficult to load this antenna, I imagine. Being an
imaginary antenna, it obviously has an impedance of z = i50 ohms.

I have both. Much prefer Autek because of its handy size. Also, SWR is
actual digital readout instead of the old usual SWR bridge dial.

Well, I purchased an AEA Isoloop a few months ago and unfortunately, the
capacitor motor was defective and it didn't turn the capacitor so I had to
send it back. I've read some good reviews of that antenna, which are what
inspired me to buy it. I still plan to give it a chance all the same, I
plan to buy another one soon.
