Digital over the air tv.

Short story....Go with the Batwing antenna. If you already have one but it does not have the side arm then add the Wingman attachment.
If you don't have a Batwing and you don't want to put a hole in the roof then buy the Rayzar.

We purchased the 1byone 70 Miles Omni-directional Amplified Outdoor HDTV Antenna Caravan TV Antenna High Performance RV Antenna, but it doesn't seem to still be available. We installed it a couple of months ago while camping in a TN State Park. We had two channels on our TV, installed this thing and got 23 different stations. We were very pleased.

Sorry but that's not at all true and any ham here that's ever worked 2mtr VHF or UHF will back that up. Line of sight only for TV is a 1950's wives tale when receive technology was nowhere close to where it is now.

When ATSC was first introduced there were people all over the country that were commonly watching the experimental stations from hundreds of miles away with good preamped antennas and 1st generation ATSC receivers on UHF. Digital modulation is often far more robust than analog at equal power and equivalent distance.

If the OP is comparing antennas, the Batwing is by far the superior antenna and depending on where you are in and around Quartzsite can see stations from Yuma and Phoenix

digital t.v. is line of sight. if your antenna can't see the stations antenna. you won't get enough signal, no matter what you use as a antenna. if you are line of sight and the station is a long distance. then a amplified or a large receiving antenna will work the best.

Height is Might (for antennas)

An antenna 2 ft above the roof will usually out perform a similar antenna mounted 6 inches above the roof.

above is better and add the sensar unit to dial in the strongest signal...

Winegard RAZOR antenna.......





NOPE---------

Sits to low
OTA Digital signals are best received via an antenna with height such as the Winegard Batwing CRANK UP antenna
