The report is a bit off -- set-top gives us only WRLK and WLTX, both spotty enough to often be difficult to watch. This is likely because we are nestled in a cove with steeply rising grade to the N, E & S. To make matters worse, at the top of the grade, a block to our ENE is a several-stories-high building, covering an arc of maybe 55-65 degrees true. This blocks most of those xmitters to the ENE.
So, I put an Antennacraft HBU33 in the attic of our shed, which is as high on our lot as it gets, and as far to the east, and aimed it to peek around the corner of that pesky building. 150ft of RG6 (no amp), and a lot of crawling around under the house to pull it through the buried flex to the shed, and Voila! We now get WRLK, WLTX, WIS, WOLO, WACH, WKTC, WZRB nice and clean. TV claims signal strength for these of "85%" to "100%".
Except...
WRLK now drops out for about a second every minute or so (seems like about that long -- haven't broken out the stopwatch). TV claims "85%" steady right up until the drop-out, at which point it drops to "no signal" and then right back up. Never more than a word or two of dialog, but nearly impossible to watch.
So, maybe some equipment on the apartment building blasting us with RFI on a regular cycle? Some sort of capacitive buildup/discharge cycle in my setup?
I'd love to put a simple UHF antenna at the other end of the shed (15ft away) aimed at WRLK with a notch filter on the HBU33, and narrow bandpass filter on the UHF antenna, but I'm guessing finding such filters would be problematic.
Suggestions?
