ON THESE THREE BANDS, the antenna we have been using (see below) is no longer considered a short antenna. It is almost full size on 30m and 40% longer than a 20m dipole, but on 40m it is about 30% too short. Normally most general purpose matchboxes will have no problem matching this antenna on those three bands and even higher bands.. Fitting the copper pipe together to make the loop shape. We used Silver Solder for our Loop Antenna joints. This requires more heat than plumbing solder. Suburbans make a. Antenna efficiency: 83% (-0.8 dB below 100%) <- this is considerably better then 40m Antenna bandwidth: 65.7 kHz <- No problem here, gives you 65khz space to move around before retuning the capacitor Tuning Capacitance: 35 pF <- take note of this, as this is the low value for your variable cap. COMET UH-9V MULTI-BAND MOBILE ANTENNA The Comet UHV-9 is Comet's latest model HF - UHF mobile antenna. Apart from 6m, 2m and 70cm, the UHV-9 comes with 80m, 40m, 20m, 17m, 15m and 10m!

Good compared to what? Well first off we will compare it to a normal whip - an MFJ-1640T, 40m monoband whip. The MFJ-1640T is about 7 ft. 2.13m tall. With this antenna my car is 4.13m high at its top - about 5 inches longer than permitted by law. MEASUREMENTS: In order to get an accurate view of the feedpoint impedance, I removed the coax from.

It might almost double the performance of the 40m Hamstick depending on your ground conditions, but it will not turn a 40m Hamstick into a good antenna. Hopefully, you have more vertical space than seven feet. Make your vertical as long as possible (up to 1/4WL). Even a 12 ft vertical will beat the Hamstick especially if you add top hat capacitance.
