Hi Ted,

I haven't looked for commercial antennas, only how to build one. For $221, I'd want a whole rig or at least a Funcube Dongle!. If you email me I'll send you some notes I did for Paul rather than extend this topic.

jimevans at callsign dot com will do it if it is not available from the user info here.

Just goes to show what notice I take of my surroundings. The antenna is mounted on a single storey block at the side of the main school building. It's our school blocking the signal! Unfortunately we are unable to have the antenna mounted on the main building. If we could then nothing would block it.

I've had acceptable success running a funcube dongle with a 1/4 groundplane mounted close to the ground in the yard with 20m of RG58. Antenna was made from 5 coat hangers using a HF wip mount. Built a tape measure 3 elem beam this week and will test that this weekend on the telemetry beacon and transponder downlink. 73's
