[BC] Antenna matching tuners: if from scratch

[Thomas G. Osenkowsky]

Are you referring to an FM antenna matching unit
at the feedpoint? If so, contact the manufacturer.
The correct way is to use a network analyzer to
examine the bandpass. There may be several
combinations that produce a 1:1 VSWR at
carrier, but the bandwidth and performance
under icing conditions may be unacceptable.
