When I first realized that I needed an antenna specifically customized for a particular frequency, I got my inspiration from this site:
Too expensive to buy a custom manufactured antenna. I built one specifically for my FOX frequency using the dimensions for whisker length and spacing suggested by this site from materials I could get cheaply at Home Depot. It worked quite well because that station went from a 17 SNR (marginal) to 25 (stable and useful). That really got me thinking about the phenomenon of frequency resonance for antennas.
Since I didn't want to overdrive all the other frequencies, I got a preamp from Jan Jenca specifically for that frequency:
All the other stations are on a different antenna\preamp. Joined the lot with a Jenca channel custom combiner:
Altogether came out to about $100 to be able to get FOX reliably and stably.
OK, over and out @RetiredEngineer, back to the "Tablo Update 2.2.18 Problem Recording" issue and good luck...
