ihave a question
i have a tait t2010 receiver hooked to a pm150 maxon (smx4450uhf)at 40
watts into a 6mc450s duplexer feeding a 6db commercial antenna .it works
fine but if we use the repeater continous for quite a while .the rx signal
slowly gets weaker
and finally pure static .we give the system a break for a bit and it seems
to come clear again
i have heared the transmitter might be heating up and this could be caused
by reflected power because of the length of cable between the tx and
duplexer isn't correct.
someone also sugested useing antenna tuners to match it
i was talking to another rf company today and they sugested to check the
duplexer to see if it is heating up which might answer the weaker rx signal
but i havent checked this .
can anyone shed some light on what could be causeing rx problem .
Thank you
Ian Wells
