This type of antenna provides 3-4 dB of gain as can be seen in Figure 1. The Horizontal Loop, also known as the Loop Skywire Antenna, is an old but very effective design. It is an antenna and circuit combination that takes account of the antenna's transfer and reactance characteristics in order to flatten out and broaden the overall transfer from wave field strength to output voltage. QUAD or LOOP ANTENNA 19-01-2011. The experimentation needed to build the first loop of my new design really paid off. When power is applied to the loop at its resonant frequency all of that power will be radiated. I had initially planned on replacing all of the mast pipe with new stuff, but after pulling the one 6 meter loop and VHF vertical off of the antenna, I figured I would just continue to use the existing mast. It is tuned to the lower portion of the 6 meter band. The inductor on the CB antenna makes the antenna electrically longer than its actual radiator length.

Hi-Q-6/160 RT MC-3H HF Mobile antenna on the top of my carport with ONLY an 8’SS whip and NO CapHat. sized antennas. Since the sides of the square are equal, this means the finished antenna is approximately 5 feet square. 10m or 40-10 meters depending on your available space. Most designed discone antennas are broadband-type antennas and generally have unity gain. Contrary to popular belief, it is almost impossible to design a remotely-tuned mobile antenna to cover 80 through 6 meters, much less adding 160 meters to the mix. See how to assemble the OA-50 (YouTube link). Currently I have been using the Icom 7000/AH-4 with about a 65' longwire at 5'. The coupling loop features a novel hybrid coupling scheme that guarantees a match of 1. That is, given measuring equipment-antennas and a field strength meter-we would have no way of knowing whether the electric and magnetic fields we measured were created by a dipolar or current loop source. ) capacitively shielded loop antenna that I developed for two meters. Silver Solder 3. Keep in mind that the pattern shown is for a 6 meter antenna at about 7 meters (21 feet or so) - or about 1. The 160 or 80 meter full wave loop (particularly the 160 if you have the room and supports) will load up nicely on several bands without a tuner, and on pretty much all HF bands with a little tweaking from a tuner. To enable disconnecting the wire, making it one long wire, rather than a loop. Cubex Company -- HF Quads as well VHF lines; OptiBeam -- Antennas from Germany! Chameleon Antenna-- An innovative antenna design for fixed / portable or mobile use, and covering 6-80 meter bands! VERY nicely made, too!. Flux and brush to spread the flux.
