coax loop antenna

G3YXM Small Loop - This simple antenna is capable of remarkable results on 160, 80 and 40 metres. Forming a triangle from around 50 feet of satellite TV coaxial cable, the top of the triangle can be as low as 15 feet, and the lower side just high enough to prevent a passer by hanging themselves

HB9MTN Loop for 6 meters - picture and dimensions of a coax loop antenna centered at 51.490 MHz

A Cost Effective Current-mode 1:1 Balun - A cost effective current-mode 1:1 balun can be constructed from a length of coax and a rod typically used for a broadcast antenna loop-stick, some electrical tape, cable ties, a length of PVC water-pipe and some connectors.

Feeder Radiation - Connecting centre fed antennas, dipoles, yagis, rhombics, loops to coaxial cable, unless care is taken, it is not difficult to end up with feeder radiation resulting in power loss and the radiation characteristics changes

A Small Wire Loop Antennas for 160 meters  ^pop - Low noise, receive only coax loop antennas for 160 - 10 meters HF bands

160 m Balanced Coaxial Receiving Loop Antenna - KN4LF explanation of the 160 meter balanced coaxial receiving loop antenna, easily adaptable to a 40 and 80 meters band

160/80m Coaxial Receiving Loop Antennas  ^pop - Receiving loop antenna for top band. This antenna allow to reduce noise on both bands. The stand alone 80m loop is approximately four feet in diameter. And made of light weight material. Which makes it ideal for portable use or you can mount it above a pre-existing vhf antenna, and due to it's small size it is quite rotatable.

LA1IC Coax-Fed slooping longwire - Simple, inexpensive and easy to erect, this antenna provides directivity, low angle radiation and a small gain on a number of HF bands.

Cheap antenna to make from 160m - 6m  ^pop - The antenna is nothing more than a simple 2.4 metre square loop drawing pinned to the internal brick wall of the spare bedroom. Yep, thats right, the inside wall of the spare bedroom - ideal for flat dwellers, hotel rooms or whinging neighbours, The loop has a simple switched inductance at the top of the square loop and uses a simple coaxial stub to tune the antenna. An additional variable capacitor placed across the feedpoint can be used to fine tune the resonance of the antenna, by Andy G0FTD
