A portable 10/20/40 mt vertical antennapop
- A portable vertical antenna for 10 to 40 meters, designed for mobile operations can be used in a car as seen in pictures. A modified version for 20 and 40 meters is described too.
A magnetic loop antenna for HFpop
- Able to cover all frequencies between 3.5 and about 10 MHz, the loop described here is directional, does not require a radial system, and stands just 1.8 metres tall. Most parts needed can be purchased at a hardware shop. The antenna can be put together in an afternoon and requires only hand tools to assemble. It should cost less than sixty dollars to build.

A Portable Multi-Band Magnetic Loop Antennapop
- Described here is a simple multi-band magnetic loop antenna designed for 20, 30 and 40 metres, but by changing the overall length of the wire coverage of other bands is feasible
Cheap antenna to make from 160m - 6mupdatedpop
- 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
A low cost 600 watt ultra-linear amplifierpop
- This compact little amplifier is the brain-child of Pat Murdoch, ZL1AXB, in Auckland, New Zealand. It is only 11" wide, 4" high, and 9" deep.
Operates for 40, 20, 17, 15, 12, and 10m
