Magnetique 27-28 MHz
The critical part on this type of antenna is always the variable tuning capacitor which is located at the hot spot of the antenna
Portable 28 MHz 10 Meter 2 Element Beam
Element is 8 ft and 4 inches long each there's 2 for a total of 16 feet 8 inches, the reflector is 17 ft and 7.3 inches long with the spacing at 6 ft and 7 inches from the driven element
Simple Antennas for 10 Meters
The Lazy H is bidirectional but offers a pleasant 6 dB gain. This could be a good project
The Homebase 10 halo antenna
The Homebase10 is a simple to make wire halo antenna for 10m 28MHz built using parts available from the local DIY store
