[BC] STL antenna mounting

[Mike McCarthy]

Steve,

I'll email you data of the Bp filter I used from TXRX.  Nary a problem in 
three years of use except for inversions.  I would also then procure a 
band-stop filter for the FM carrier.  A 1/4 wave stub on the FM channel 
might also do the trick between the filter and RX. Use a signal monitor and 
trim for deepest rejection. Or use a trombone section to trim.

Also, if you can, install a 2nd RX dish 50-100 ft. lower and switch between 
them as needed for diversity/inversion rejection.
