Antennas : 15M
- DX Dual Dipole
pop
- Two dipoles fed from the same coaxial line by n6bz for 20 and 15 meters
[Hits: 27416 | Votes: 15 | Rate: 4.12] Antennas : 17M Antennas : 20M : 20 meter Dipole Antennas Antennas : Baluns Antennas : Bazooka Antennas : EH
- EH antenna power lost considerations
- Out of Balance Current or Longitudinal Mode Current in the Coaxial Cable causes radiation from the coax. But how large a proportion of the total power is radiated or lost from this Current?

- Cebik Moxon Rectangles
- The Moxon Rectangle is growing in popularity as a compact 2-element array that approaches a full-size 2-element in gain but with a far superior front-to-back ratio and a direct match for the standard 50-Ohm coaxial cable.

- 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.

- 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
