Question Inverter Cycling Fan / HDTV issues

Noticed this weekend that a cycle of 5 seconds on / 15 seconds off the fan of the inverter (?) - the fuse box below the fridg - would run...but only when the awning leds were lit. (it was nice to be able to use this new camper, even in 95* temps). The awning replacement worked well; nothing leaked; the a/c was cold...oh, one thing...the HDTV signals....sucked. One channel scan would "find" 14....but only three (weak) broken useless pictures. The next scan would fine 5...useless pictures. Any suggestions on antenna issues (we're camping at Kerr Lake...hardly remote or distant from civilization)

You must mean the CONverter, not INverter.

Usual reason for the cycling, is a bad battery that the converter keeps trying to recharge.

On your TV antenna, let's review a few things.
1) When watching Over The Air (OTA) digital HDTV, you need to either point your directional antenna (Winegard) in the direction of the tv stations you're trying to receive or have a fixed base antenna that is capable of receiving signals in a 360 degree radius.
2) Before you do your channel scan for OTA channels, you need to push the button on the antenna amplifier. When it's on, typically they have a green light that is lit. You can now go to channel scan, be sure you are on set to "AIR" and perform the channel scan. Wait until the scan is complete, don't interrupt the scan while it's in progress as you probably will lose those channels already scanned and have to rescan.
3) If you are wanting to view cable channels, you will need to turn OFF the antenna amplifier, go to the scan menu, make sure you are set to scan "CABLE" and do a channel scan.

If you do these steps, you should have no problem viewing the available channels with OTA or the campground Cable system.

Ahh, the joys of recreating. The battery is "new" - in use since April...but with a 2016 build code date. Always well watered and generally on line with 110v ac source. I really hope it's not already "dead" or dying. And odd, that the converter fan only cycled when the awning leds were lit....
The antenna is (no surprize?) not adjustable. It's a bat-wing type and me-thinks pretty low-quality. Shopping for a better antenna right now. 10-4 on the scan and amplifier power. Odd that some scans would "find" 10 - 14 channels, yet none would reliably play. . .lots of digital noise...even tried shutting off fans, etc to see if there was RF interference.
Oh well..it's a learning curve...

I've owned RV's with the Batwing, the round flat antenna that rotates inside, the Jack and the Winegard. The Winegard is far and away, the best RV antenna we have ever had/used on any of the 12 RV's we've owned. If you actually replace the batwing, I strongly recommend the Winegard crankup antenna with the Winegard Wingman accessory attached!

Not necessarily "odd, that the converter fan only cycled when the awning leds were lit." Even with a good battery, an extra power load (running awning LEDs, for example) will cause a converter to wake up and back-fill used up power. Any item which uses enough extra 12v power will cause the converter to charge and thus cause the fan to run.

You probably have the cheap Chinese knock off antenna and they perform poorly. Here is the only info out there on that ant.
Sounds like turning on the LEDs with the other 12v Draw is causing the total 12V current to be high enough to ramp up the converter. The fan is temperature controlled so as the current increases the temp rises and the fan turns on, Not unusual for high current. Check the LEDs to insure there isn't a short.

Do you have a residential fridge? If so you have an Inverter. Many of these units are being ordered with residential refrigerators.
