Im seeking best practice or your thoughts and suggestions on where to place the above items in the coax cable run.
Firstly, Im aware that some Active Antennas require grounding and assume this is for some protection against static spikes / voltage surges etc. Im also aware that most professionally installed' radio antenna systems have a voltage surge /static discharge grounding near the point where the coax leaves the tower or mast and a ground wire continuing down to an earthing point.
So would best practice be to have the 1090MHz filter at the antenna end ? or inline somewhere along the coax run ?? or immediately at the receiver input ??? And the same questions about where to position the surge/static protection.
Given cable loss factors and limiting the number of connector joins, would a solution be to connect the antenna filter directly to the antenna, then connect the surge/static grounding block to the antenna filter, with the ground wire to earth, leaving an unjoined coax run directly to the receiver? Or does it matter where they go as long as they are installed somewhere ?
Cheers
Peter
