432 MHz EME with a small antenna
by Andreas Haefner, DJ3JJ
A lot of people would like to do EME but think they need a big antenna for this. In this article I show how to build up a small but competitive EME antenna and what is important to be successful with a small station.
1. The max. possible boom length that works without mechanical support and ended up at 3.4m (4.9wl) with a 20 mm x 20 mm x 1.5mm boom.
2. Solid aluminium elements with diameter of 6mm to reduce wind load and allow easy screw fixing.
3. Elements mounted on top of the boom with commercial element holders.
4. Z = 50 Ohm to use an easy to build straight dipole.
5. Symmetrical dipole made from ½ inch cellflex cable.
