This chapter discusses the large loop antennas, of which several varieties for both transmitting and receiving are covered. The quad loop antenna is perhaps the most effective and efficient of the large loop antennas, and it is certainly the most popular. The quad loop consists of a one ...
Loop antennas like these are typically used only for receiving, but in a pinch they can be used to transmit as well. To tune the antennas, which are much shorter than a standard vertical or dipole, a capacitor is soldered onto the ends, which electrically lengthens the antenna. [OM0ET]...

Loop antennas are great for situations where space is an issue or when one has interference that is from a point source that needs to be mulled out.Passive loops are no substitute for a full size resonant antenna. Reply #13 on:January 20, 2016, 06:29:05 pm » Sue, what kind of ca...

The antennas are: –TheWellbrook FLX1530LNwith a 1 meter diameter loop of LMR400 coax. This is my “standard” portable antenna (I use a telescoping broom handle for the support; I wrote about it here as the “signal sweeper” last year). Excellent performance, but on the bulky side fo...
There are times when it can be beneficial to use separate antennas for transmitting and receiving. As an example, a vertical antenna can be a great radiator on 160 and 80 meters, but it may also be a very noisy receiving antenna. Thus, s... A Phil Salas - 《Cq Amateur Radio》 被引...
Here is your guide to large and small loop antennas for transmitting and receiving. A comprehensive aid to understanding and building loops for longwave, medium wave, shortwave and VHF. Loop antennas can be very effective, even if you have limited space and a tight budget. Many diagrams and ...
