Good advice from ADTech and Tower Guy.
Your FM signal report; the second strongest FM signal report I have ever seen:

Very likely to cause interference to TV reception.
You must ground the coax with a grounding block connected to the house electrical system ground to make the FM filter (or two FM filters in series) effective.
If the antenna is outside, the coax shield should be grounded with a grounding block that is connected to the house electrical system ground with 10 gauge copper wire for electrical safety and to reject interference. For further compliance with the electrical code (NEC), the mast should also be grounded in a similar manner to drain any buildup of static charge which will tend to discourage a strike, but the system will not survive a direct strike.
Unfortunately, FM filters are no longer in stock at Antennas Direct. I hope they will reconsider their decision not to carry them anymore; they were the last remaining regular supplier of FM filters.

It is now necessary to scrape the bottom of the barrel, or use a HLSJ, high and line ports, that is also hard to find.
