[TenTec] Antenna Analyzers

[Bill Fuqua]

Analyzers have been improving over the years. The ones had were  the first 
ones off the production line. This last one is fairly good. If  they used 
better detectors and bridge circuits they would be much more accurate. The 
that is fried is a plain 259 no a, b or c.
It does not have a PIC microcontroller in it as in the schematic down 
loaded and the display board seem to be made by some other outfit. If the 
controller is fried may be out of luck anyway. But never the less. Some day 
I'll get back to it.
As far a GAP goes. I think some of their advertising is snake oil. About 
how they get the signal high in the air over near by houses to prevent TVI 
and stuff like that. I'll take a good old Mosley any day.
