I have recently purchased an early Monaco class A coach that has a Roadstar RV-3800 antenna on it. I am not new to RV'ing by any means but all my past rigs have had your Sensar amplified directional antenna's. I know that an omni-directional antenna will not perform as well as a directional one but I have another problem that I am unable to figure out!
At times the Roadstar performs very well and at other times the signal drops right off. Where we are camped TV signals are generally very good, even DTV signals. The first time it happened was when it was very windy (were right on the Atlantic coast) so I checked the connection on the antenna itself. This corrected it for a while but it happened again the next day. I checked the antenna connection again and even replaced the connector on the antenna. Again it corrected the problem until the next day. Again I checked the rooftop connection but this time it did not help! I then checked all the connections from the antenna right thru to the TV, including the HD converter box. Nothing made any difference so I verified that there was voltage to the antenna using a home made test light soldered to a F-connector, again everything checked out okay! I then ran a temporary coax from the booster to the antenna hoping to find a bad feed cable, again nothing!
When this happens the onscreen signal meter (from the converter box) jumps all over the place sometimes going from 1 to 100 and all in between, normally the signal strength maintains fairly steady with only a 5 to 10 point difference even when it is extremely windy!
Is is possible I have a bad or broken connection on the inside of the coax feed on the Roadstar? This might explain why it worked the first 2 times I moved the antenna connector on the Roadstar itself ???
Other than this problem the Roadstar performed very well and I would like to keep the omni-directional antenna if I can resolve this issue!
I hoping you can give me some insight or a solution to this baffling problem
Thank You, Ken
