Frustrating Antenna problem

Brand new 2017 Keystone Outback TT. I was on my regular trip to ME for a week. First Day I setup and let the TV auto-scan....I get a number of channels all nice clean ( it should be its all digital) a day or two goes by we have a night of heavy rain and the next morning no channels. Try re-scan I get nothing or maybe 2 channels weakly. Check the booster...light is on...go up one the roof. I pull the antenna check all the connections....getting 13.4V on the Coax....Can't find anything obvious. Check all the connection I can get to all seems normal. Hooked the cable TV up shut the booster off and that works fine. I even ran a line directly from the TV to the antenna...no joy. I thought rain shorted something out but I didn't find any evidence that water got in anywhere and I have a surge suppressor on the shore power. My guess is something just failed on the antenna circuit board.

So I can try and call the dealer but I know they are just going to tell me the stations are just our of range. At Home it pulls in one channel and should pull in at least 3, I know for a fact one missing channel is on the same tower as the one that does come in. Perhaps a certain frequency rang went bad.

This is a low profile antenna and isn't' really available anywhere other than Ebay. Part of me just wants to replace the whole thing.

Any advice is appreciated. I'm pretty tech savvy and worked broadcasting operations for years so I get how this stuff should work.

This is the model I have RV Omnidirectional Antenna (CA-1500) - Continu.us

Thanks

low elevation,
low performance.
Wet Trees . etc , reducing signal.

you may want to replace to a directional Bat-wing . or similar
. I just upgraded from a Winegard 2 to a Winegard Sensar 4.

Two things:

That antenna is very poor, get a real one.

If you have any LED lamps, turn them off, re-scan and try it with them off.

For the best possible OTA TV reception you need to swap that Omani-directional antenna with a Winegard Sensar III "batwing" antenna:

Our antenna will not work with the ceiling fan running.

Thanks for the reply. I realize reception can be affected by many environmental factors. Just seemed really odd that one day get 10 channels and the next I get 0. The coach didn't move the weather was clear and I was in an open area near the shore.
I have emailed the manufacturer and there response was to show me the towers in the area and how far they were. Implying that anything beyond 25 miles is out of range....which is BS as most stations coverage is far beyond 25 miles.

It looks like a replacement is in order which will require major re-work of the mount since the antenna I have was low profile and has a proprietary mount.

Works yesterday, heavy rain, then doesn't work today....I think that's a clue.

Since you are tech-savvy and can get on the roof of the trailer, is there any way you can open up the antenna to see if there is any water in it? And, a green light on the booster and 13.4 V on the coax doesn't mean the booster is working. Stuff happens.

See if you can get the dealer to swap in a good booster (easiest), and if that doesn't fix it a new antenna.

Good luck!

Yup did that yesterday no evidence of water intrusion or fried circuity however it only takes one little diode or cap to fry and you can't tell by looking at it. I may try an aftermarket booster and see if that helps.

Thanks

Loose the Omini and get a directional. I had a Jensen Ominidirectional and replaced it witha King Jack antennae because it was easy to install the base in the same place, and I didn't have clearance for a Wingard folding to fit.

Weather can severely effect reception. Clouds actually help reception because the signal can bounce off them and back down to earth allowing a longer distance for reception. Rain interferes with the distance the signal can travel. It isn't at all unlikely that you get signals one day and not the next.

A better antenna can definitely help. Directional is the best bet.

Did more testing....I guess the system is working as designed. Perhaps all my cable tightening improved things. Here is the odd thing. I am just barley picking up a tower that's about 20 miles away. However I know that there is a hill blocking direct line of site and I am probably picking it up off a bounce. Here is the odd one and this is whats telling me the system is working. I am picking up a tower 54 Miles away clear as bell. Obviously there are no obstruction between the antenna and the tower. Since we are just weekend campers and many campgrounds have cable I'll live with the current setup. Thanks for the input.

You could put some of this on the antenna coax connection (Amazon or ham radio supply shop). Works well, a little messy to remove though. VHF/UHF signals require line-of-sight propagation. Will go a long way if there are no obstructions (like hills).

Omni directional's are nice for easy of use but most of the time not as good as a directional antenna. I have a directional in mine and when i get to a campsite I use a free phone app called TV Antenna Helper. It finds my location then it tells me which way to point my directional antenna. So far it's worked very for me. I think you will have better luck swapping out that omni. Also make sure your amplifier is turned on.
