Switchable Antenna 80/160 meters band Priority listing - A switchable antenna for 80/160 meters by IK1ZOY. A new version of a 1/4L 80 m. dipole modified for use in 160 m. band. using it's own coaxial cable feeder to wrap a coil.

Double bazooka coaxial dipole antenna  ^pop - From WH2T Dr Ace's Double Bazooka Coaxial Dipole

The Double Bazooka Antenna - The Double Bazooka Dipole is a very efficient single band antenna which is very quite, and does not require the use of a balun. This antenna consists of coax (RG58) or other 50 ohm type with the shield split at the center and the feedline attached to the open ends

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?

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

The Multi-Band Fan Dipole - How to build a multi-band dipole antenna with a single coax feed. Instructions for a 160M antenna that will fit in the space that a 75M dipole will with almost as good of results as a full size 160M dipole!

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
