I have played with BATWING, JACK, OMNI Hide-a-antenna, BOW TIE Panels, and LOWES BEST VHF/UHF long YAGI.
The LOWES multi-dipole YAGI $80 did the best.
This antenna pulled in some real good signals and by adjusting the positions of the fold-out dipole it worked great with distance and more local station. Was a sight to see however extending 6-feet or more off both sides of my POPUP roof and when I rotated it I was always hitting trees on both sides. Folks lined up however to watch me play with my big antenna...
After about a year of using this antenna I finally totally destroyed it by having to fold-it-out at every stop and the aluminum dipoles finally broke beyond repair.
As shown in the easy-up mount above you can see how I rotated my antenna by just reaching out the window flap of the POPUP and turning away.
The OMNI Hide-A-Antenna as it is called does work but suffers big time on reception. This is basically two DIPOLE in opposite directions and doesn't work well with distant stations. It also suffers big time of losing the digital signals from the HDTV station when aircraft fly over head. This is my BACK-UP antenna as it disappears into the tube and is great for storing when in travel mode.
I then picked up the BATWING and the JACK and mounted them on my easy up pole mount. They both worked great but the BATWING had a wider beam-width allowing me to pick up more HDTV station that were in the same direction but located on the different sides of the town. Washington DC is some 50 miles from us here in Northern Neck VA and they have their transmitting antennas on the NW and E sides of town. We would have to move the JACK antenna to pick all of these stations up. The BATWING would get both groups with one pointing location in this case. The BATWING is the antenna I use today. Easy to transport in my case and I mount everything up and start watching TV in only a few minutes after arriving at the camp sites.
I would say the KING JACK antenna has more gain but you really have to point this antenna towards the transmitting station to get best results.
ADDED NOTE: SCFJEFF reports down the thread here I am wrong with my assumption that the JACK Antenna has 'LESS BEAM WIDTH' then the BATWING. I was just reporting what I found in my very simple pointing antenna tests I did here. That may have been a wrong assumption on my part. All I know is the BATWING outperformed the JACK antenna in my case looking at several HDTV Transmitter stations situated on both sides of Washington DC some 50 miles away... Sorry if I mislead anyone here...
The JACK antenna will mount on the BATWING hardware and crank-up and rotate just fine using the BATWING controls. It also can be mounted just above the roof and only rotate. Like said above being close to the roof makes the JACK suffer from performance somewhat and even things like the roof mounted air conditioner always seems to get in the way when you are trying to pick up a TV station in that direction. Being up as high as you can get worked great for us but I didn't like the very narrow BEAM WIDTH I was getting with it in my setup.
I also experimented with the BOW-TIE PANEL antenna. This is a panel about 3-feet by 2-feet and has 8-BOW TIE dipoles on it. This is a great antenna and is more suited for the home installation. You can mount this on a single pole so can be used on the RV as well...
This is probably the best of all antennas as it has great performance in picking up station up to 75 miles away. Also has great signal reduction to the rear of panel... I use mine here at the house and and the two array panels can be pointed in different directions and this really performs well pointing to the Washington DC digital station which are some 50 miles from here... This array panel was just on sale for $49 Extremesignal recently. I originally paid over $100 for my panel from a different company. I am a sucker for deal hehe...
