Well....Here's the update:
New 7 ft. J-pole antenna was installed next to a copper roof
This affected the signal strength of the N90 freqs and when I couple the old and new antenna's together should fix the problem if too much signal isn't lost in the conversion.
Feed will be tuned to 119.4 (DXR ATCT) tomorrow from 7:30 until 12 noon PM EDT for recording purposes and will go into full op. in the regular band after 12 PM EDT.
