[amsat-bb] Sat-Antennas ...?

Hello... if somebody has experiences for the satellite radio over present, functioning amateur radio satellites with the following antennas:

EB-144 M2 und EB-432 M2 (following the Link) ???

Dignity these antennas is sufficient around more or less adequate company to be able to do over the satellites available still nowadays, without rotors, however, with preamplifiers... or would you advise me against the investment in these antennas from the start??? Use here an IC910H.

I have worked during earlier years very well with the MASPRO antennas and rotors, now might, however, again - with as low as possible expenditure- get into the amateur radio over satellite.

Thanks for answers , Jens / HB9JOI
