I depend on an OTA antenna for all my TV programming. From the antenna, there is coax going to the outside part of a signal booster, then coax going down into the ground, through my foundation wall, into the crawlspace, where it connects to the inside part of the signal booster. From there it goes about 40', through the crawlspace, up inside a wall, to a faceplate where it connects to a female coax connector. On the other side, the cable goes to a splitter and into two HDHomeRun quad tuners.
Originally all the coax was RG6, but I changed it to RG11 last fall. This spring, on hot days, I would lose the TV signals until in the evening when things cooled down and I could get a signal back. I talked with a tech where I got my antenna and he said they've seen this before, with RG11. The conductor is larger than the conductor in RG6 and stretches the connectors. They sent me a new antenna (at no cost).
He said a big issue (that they've seen before) is that the RG11 conductor is notably thicker than the conductor in RG6, so it tends to expand the female connectors to the point where the connection is not as solid. He said that if I have RG11 in place, it helps to use short RG6 cables to connect to my devices so the connectors in the devices aren't ruined.
I do have a few components with female connectors that have had RG11 cables in them. If that's stretched out the connectors, what do I do if I need to connect some RG6 to them now? Can I do something like insert some aluminum foil to fill the gap and provide a better connection?ler conductor where it connects to the booster.
I'm open to other ideas about whether to use RG11 or RG6, but with some of the weaker TV signals, I got better signal strength in the house when I upgraded to RG11, so I don't want to just replace all the RG11 with RG6, but I'm worried about this issue of the RG11 having stretched connectors on some of my components.
Are there other things I should be considering to deal with the issue of smaller RG6 conductors in stretched female connectors?
