I use the BATWING with UHF dipoles on it... Does pretty good for us here on East side of the US where there are lots of towns that broadcast the new digital HD TV signals... Out West it was somewhat spotty to pick up HDTV signals from the local towns when camping way out somewhere. The beam width is fairly broad and don't have to move the BATWING antenna much when changing stations. Most of the time the Digital HD station are from the same local town antenna. Using the BATWING I get alot of fading when airplanes go overhead and with different weather conditions if the tranmitting antennas are 40-50 miles away.
My basic setup using a quick setup rotatable antenna pole for my HDTV antennas on the OFF-ROAD POPUP trailer. It is neat as I can reach out thru the window flaps and rotate it haha..
I did pick up one of the KING JACK antennas smaller footprint antenna and it seems to have a better signal but is very narrow beam width. You really have to be pointing right at the HDTV transmitter antenna real close to work good. Here where I am south of the Washington DC HDTV towers I have to move the KINGs JACK Antenna to get all of the NATL BROADCAST TV stations. Washington has towers on both sides of their district.
I also have one of these DUAL DIPOLE antennas mainly for a back up and this doesnt do very well for me. It does work however in a pinch...
I had one of those CHANNEL MASTER LOWES $80 house YAGI antennas up for a season which did a real good job. I finally destroyed it by taking it down all the time and folding it up for transport. It was longer than my trailer was and sometimes I couldnt swing it around for hitting trees close to the trailer. Everyone that saw it on my POPUP trailer always had comments to make haha... This was a gang busters antenna before the NATL BROADCAST changed over to digital TV mode and dropped the LOW BAND VHF frequencies.
The best reviews I am reading now is for one of the Antennas Direct DB8 UHF BOWTIE type antenna panels. This would be mounted on pole outside your trailer and is not too large of an antenna setup... Uses a pre-amp... Having the two sides angle adjustable helps with having slight two different angles at the transmitter location for me without moving the antenna. Being a good UHF antenna it does take good pointing to work. This one solved my problem of 60-70 miles away HDTV reception. My BATWING does pretty good at 40 miles away. This Antenna is available from AMAZON. Search for DB8 Antenna... Not sure how this would look up on the trailer roofs but works great on my POPUP trailer easy up pole... Measures 28.5 x 42.9 x 9.1 inches - 7.8 pounds... Since this is made up of antenna mesh it does not have much a wind load affect when the winds get up at the camp site.
Hope this helps some...
