Unfortunately, we don't have the info on the antennas, but both were bought at Radio Shack (the house one is bigger than the outbuilding one) and were told these were the best for our situation. --and they were--til a month ago. The smaller one had been working for 4 years.
He tried connecting a 2nd coax (not exposed to the weather) directly to the house antenna. BUT, we did not do a channel scan at that time. We will have to repeat that test.
How can cable be protected from water when it's connected up in the air and exposed to weather?
Just a side note: Today he tried our small TV in our RV that has a Winegard amplified antenna that also used to get reception. No dice.
