Re: [TenTec] Orion Mic Woe's

["Tommy" <aldermant@alltel.net>]

Unfortunately it could be both! At the end of a dipole is very high 
voltage and if it hangs close to the vicinity of your shack, it 
could induce RFI. Same thing for feed line, every odd quarter 
wavelength is a high voltage point (assuming a dipole), so if your 
feedline is an odd quarter wave length at the frequency your 
operating, and that is in your shack, chances of RFI are pretty 
good. With feed line however, if that is the problem, it can be 
pretty easily fixed by just changing feed line length.
