Some people even use it as a base station when restricted space is a concern. Recently I've been fielding service problems from people using 88-foot long dipoles. Just remember that any antenna is better than no antenna. 11ac Wi-Fi coverage in a single, low profile housing. Feed triangular loops either at a corner or in the case of apex-down loop, at the apex. Many designs have been studied in order to improve the performance of multiband antennas such as multilayer patch. Whilst they will operate even if just a single copper earth rod is used, they work much more efficiently if radials are added. As such they take up very little space. Use features like bookmarks, note taking and highlighting while reading HF Antennas for Limited Space (Amateur Radio HF Antennas Book 2). Evolving from a simple end-fed Marconi for 80m, the idea was to use the opposing harmonicrelationships of two ¼ wave elements so that they could be fed on odd harmonics without. Lightweight Aluminium Roof or Ground Mount Radio Tower/Masts. Conceal, disguise, temporary or make small? Concealment means place the antenna where it won't be seen, eg inside a roof or hidden in a tree. CPI ASD will acquire Viasat's 6 meter to 18 meter multi-band antennas, providing a valuable extension of. I'm almost lazy enough to buy one, but it looks like the parts count would only come to $10-$20, and I know I have a soldering iron somewhere. Then there are some with small. While 1/8th wave works reasonably well, better coverage is obtained if the antenna is mounted at about 1/20th wavelength above ground.
