David, there is already an HF monopole (15-30 MHz) installed on the ISS has been since the early days. I gather there are antennas for HF, 144, 435 feeding into the Russian Service Module and antennas for 144, 435, 1260 (2 antennas) and 2400 (two antennas) feeding into the ESA Columbus Module. Some info on the Russian Service Module antennas at http://www.marexmg.org/hardware/antennas.html 73 Trevor M5AKA _______________________________________________ Sent via [email protected].
