[BC] Directional Antenna Proofs

[Mike Vanhooser]

If it is that old the problem could be ground system deterioration.  Just because the numbers are right doesn't always mean anything.  I have had a station recently with all the numbers right on, and half the ground system missing (thank you copper thieves).  If you don't have a complete counterpoise which is not corroded, and good grounding at each tower (radials alone will not always give you a good ground), then coverage is going to degrade.  A station which is 40+ years old can generally benefit greatly from a new ground system.  I know theory doesn't support this, but reality does.
