I've been tracking your posts and the replies, as I may soon help a coworker try to pull in our market's RF 13 signal from their cottage which is out-of-market. I have in mind to recommend the 30-2476 to them.
But, I have a theory from my novice knowledge related to your location and RF 13. I'm wondering if you're having FM radio signals giving you second order harmonics? Man, I sound techie.
If you have strong nearby FM signals from 105.0 (so 104.9 officially) up through 108 (okay, 107.9), their second order harmonics hit in RF 13's range of 210 to 216 Mhz.
Both the RCA Preamp and KT-200 mention having FM Traps, but neither provide specifics on how much they attenuate (block) the signal.
Out of curiosity, when you had the 30-2476 on the roof, did you have a preamp in-line? If not, I'll point out any FM signal would be getting gathered in.
Then, when you moved back into the attic, perhaps that provided enough "environmental attenuation" of any local FM source in your area that it helped with the improved RF 13 reception.
Using just your zip code in both FMFool.com (which is likely also out-of-date, and lacks FM translators) and radio-locator.com (which only provides vague signal indications), it looks like you might have local broadcasts within the FM 105-108 positions.
If you care to spend a bit of money pursuing better FM suppression (which likely won't help, but we don't know), about the only place I know of that still has a full-FM-band filter in-stock is this place in Canada:
When I ordered 3 from them 14 months ago, it was about a month before they processed the order and sent a tracking number. Then it was about a week to get from their place to mine (in Michigan).
Again, I'm likely sending you on a wild goose chase--but wanted to float the thought that possibly the FM Traps in the preamps are doing you some good.
