I have been thinking of putting together a fully fault tolerant tower setup.
1 antenna; two radios. Separate CAT5, separate box. If one radio failed, the other would come on-line. The replacement climb would be taken out of the EMERGENCY category. A complete system would be a 3) 5.8 120 degree sectors, plus 3) 2.4 (or 900 MHz) degree sectors. 6) small waterproof enclosures would contain a router and one of each radio. I know on some of the MT router boards there is a fan header that could be used to energize a relay. Microwave relays are readily available and have acceptable insertion loss. Would a stripline divider like Cameron suggested in another thread be the answer instead? Passive solutions are always better. If the antennas were dual-band, wind load on a tower could really be lowered. Besides redundancy, consolidating wind load would be my goal. Has anybody done anything like this? Can't seem to find any on the net. Am I mad? Mike -------------------------------------------------------------------------------- WISPA Wants You!
