[TowerTalk] Fwd: 160 vertical question (Top Hat)

[Hans Hammarquist]

 Isn't there some restrictions on structures that can effect the field-strength when the structure is near a BC station? I want to remember that if your tower affect the field-strength distribution of a BC station you have to take measure not to disturb it.


I am sure, if you have any sizable voltage/current induced by a nearby BC station you certainly change the radiation pattern from that station.


Just something to be aware of.

When the T-top is resonated into the BC band, be prepared for some very high base voltages if it's located anywhere near a BC station at the top of the BC band.   The better CIA and VNA devices can be operated in these conditions and still provide valid measurements.
