hi david,
if it is a problem of equipment, then nothing to make separately replace them, in any case it is what I believe. on the level of the TRX there, I do not know large thing but also concerning the antennas, re-examine his profit. if that dropped, then replace it with another having a higher profit. with the feeder, check their point of fixing, that can not not be made well. I hope that I am made understand. the remainder I do not know of it great trick and patient you somebody will give you your
answer.
