  • Dear Sir, I am auditing the antennas systems for one of our customers who has some 4.5m Probecom antennas.These antennas are operating with Linear Polarization. Can you please confirm if this feed can be switched to Circular Polarization? i can share some photos for the antenna and the feed. Can you please share the prices of the 3.7m and 4.5m C Band antennas , 2 port , fixed , with the Mount and Anchor rods. Noting that I tried to download the antenna manual but I did not succeed.
