This is the compact dipole used for HF communications on the set of the ABC Television show Last Man Standing with Tim Allen. The crowded space above the set required a compact multi-band dipole, and the CHV-5X was selected to solve the problem the minimal space presented lower HF bands, and we may use bare or insulated wire. Often, we mislabel multi-band doublets as dipoles because the antenna is about 1/2-wavelength at the lowest frequency of operation. But to be strictly correct, that antenna is a dipole only at the lowest frequency of use.

  1. Since our HF bands are harmonically related, this length of wire covers all HF bands from 80 mx up to 10 mx, including the WARC bands. If the wire is cut for the 40 metre band, about 44 metres of wire or slightly less, the antenna can also be used on all the higher HF bands
  2. A Doublet antenna is often used very effectively as a multi-band HF antenna by many amateur radio operators. It consists of a dipole like geometric structure but the wire length is not resonant on practically any of the operating bands. It requires a certain length of open-wire transmission line connected to the feed-point of the antenna

My homebrew vertical multiband hf antenna. April 22, 2008. November 1, 2019. - by Joost - 29 Comments. First I tried to build a Cobwebb antenna. It is a small antenna and rather easy to build. I used cheap fishing rods, costing 4 to 5 euro each, from a known sports hardware shop. The funny thing was when I asked the sales person if the rods. Workable: Attach counterpoise stud to a good ground rod at the feed point of the antenna. Note: Short antenna lengths will never be capable of performing as a highly efficient antenna. The intent of this unun is to allow full HF coverage for portable applications or in restricted installations such as HOA managed communities It covers six bands, 20m-10m on HF, and also 6m. It is a Boomless (spider quad, gem quad)design. It uses Glassfibre arms (a must). It uses a single coax line to a homebrew antenna switch. From there, a seperate feedline goes to each of the Driven Element feedpoints. There is a homebrew Choke Balun at each feedpoint. Performance Most commercial antennas specify their band width at the 2.0:1 frequencies. On 20 meters, these monoband dipoles measure 2:1 at 13.380 and 14.775 for a band width of 1.395 MHz. For 10 meters, the frequencies are 27.265 and 30.336 for a band width of 3.071 MHz. This is for thin wire elements, not large aluminum pipes

Many amateurs are very restricted with the space they have available for HF antennas.

You can also enjoy multiband performance without traps, coils, fans or other schemes. Simply cut two equal lengths of stranded copper wire. These are going to be the two halves of your dipole antenna. Don't worry about the total length of the antenna. Just make it as long as possible 80/40/ (15) Multi band dipole antenna kit, including 150 Watt 1:1 BalUn. The 80/40/ (15) Multi band dipole antenna is a half wave dipole for the 40 meter band and a shortened half wave dipole for the 80 meter band. The shortening on the 80 meter band is realised by placing two coils in the antenna. These coils also work as a high resistance. HF Yagis. View as Grid List. 17 Items. Show. 20 40 100 All. per page.
