dual band cheap yagi
by Howie DeFelice 01 Jul '10

01 Jul '10

I built a dual band VHF/UHF cheap yagi with 3 elements on VHF and 8 on UHF. I cross drilled the 3/4" PVC pipe boom and mounted the elements at 90 degrees from each other. I made the VHF elements removable so that I could easily transport the antenna in the car. I saw no interaction between the two antennas. I can definitely recommend this as a feasible project.

HF Satellite Relay
by Robert Bruninga 30 Jun '10

30 Jun '10

Heard today of a Passive HF relay satellite being proposed. Wondered if Hams could relay off of it. It's a 10m diameter sphere. I assumed a 10m signal and 1000 Watts And antenna gains at both ends of 10 dB. Unless I made a dumb error, it looks impossible? I get a received signal of -170 dBm Compared to a good HF receiver of -122 dBm So its 48 dB down in the noise. Going to narrow band, could improve things, but the Doppler of +/- 600 Hz would make that difficult. Anyway, if someone else wants to double check the link budget using the radar range equation, go for it. The beauty of this system is that it is perfectly spherical, so the reflection coefficient would be constant within 1 dB. That is the advantage over trying to use the ISS or other large rocket body... They vary by 20 dB making communication by reflection impossible. Oh, and it would be in space for 30 years or more. So with something that reliable, it would be worth developing an amateur capability to use it. It is not designed for comms, but as a calibration sphere for over the horizon radars that have LOTS more power and LOTS more gain than we do. Bob, Wb4APR
