We have a 450b high gain shipment that a large part of these devices we’ve noticed aren’t getting good signal at relatively short distances. For example, at 2.8 miles registering in a Medusa, we were getting very poor modulation and SNR signals with three 450b of the same batch or shipment. Like I said before We’ve tried three different 450b antennas, and the same thing happens with all three. We switched to a 450d, and with the 450d or old 450b, we’re getting signals appropriate for the 2.8-mile distance. What could be happening with the 450b devices? Have you had the same problem with 450b equipment? Could it be a calibration issue, since we see a big difference between the two polarizations?
signal with one 450b affected:
signal with 450d same location:
- signal difference between polarizations on 450b:
Thank you
