We are using the antenna combiner PA760 with the antenna PA805 connected to PSM700. I'm using 7 units connected to two combiners. My questions are:
1) What is nearest distance you recommend between two antennas?
2) How long of cables can I use between the combiner and the antenna? This is a fixed installation and the distance between the monitor world and the antenna is about 25 meters. I am using RG58 with the 10 db loss with 100 Mhz.
3) The antennas should be mounted 0.5 from a wall of wood. Can you help me ??
1) One meter.
2) It depends upon the cable type. 30 meters of RG8/U has 4 dB of signal loss at 800 MHz; this is OK. 30 meters of RG58 has 18 dB of signal loss at 800 MHz; this is NOT OK.
3) This is ok.
