[TenTec] 95% Shield

[Chuck & Vicki Tifft]

That is why I said well designed, and I know there are many out there , that 
are not...At one of my former sites, we had a couple lease towers.As part of 
the lease agreement all transmitters were required to have filters and 
isolators. We had about 60 or 70 percent compliance. All I could do was 
threaten, because in reality I would have been hard pressed to explain to 
the station owner why I threw out a paying customer, for not obeying my 
rules when his rent was always on time.
