I am in the process of trying to set up a station here and have been researching equipment. While I suspect there will be a fair amount of variety, I am curious to the responses to my question:
Do you use the relatively less expensive “indoor” NON RF switching preamps in an enclosure near the antennas (on the tower) with RF relays and with a sequencer in the shack (do the preamps holdup up on the tower even if protected?) OR
Do you use RF sensing preamps mounted at the tower OR
Both (for those that are extra careful)? I suspect operators that do other VHF/UHF low signal work tend toward sequencers (one for 2 meters and one for 440), i.e. moon bounce, meteor scatter, etc.
Also, I am curious what type/brand/model of RF relays folks use?
As usual, I really appreciate your time.
