bigjim Posted May 11, 2019 Report Share Posted May 11, 2019 Is the built in tv antenna signal amplifier testable without removing it the outlet? Not the 12v power outlet. Link to comment Share on other sites More sharing options...
Kirk W Posted May 11, 2019 Report Share Posted May 11, 2019 Other than turning it on and off to see if TV reception changes, I don't see how you could.

oldjohnt Posted May 11, 2019 Report Share Posted May 11, 2019 Sure there are inline coax signal strength meters one can use BUT you have to gain access to the darn unit and coax connectors AND THAT CAN RANGE FROM A BEAR TO NEARLY IMPOSSIBLE LOL. BUT if you can easily get there to bypass the amp and observe the TV for differences if the amp is used or not used, YOU DONT EVEN NEED A METER. Most have an On Off switch. In 49 years of RV use I've observed more problems in the cables and terminations and connections then those amps, and its usually on the rooftop.

Dutch_12078 Posted May 11, 2019 Report Share Posted May 11, 2019 If you're referring to the amplifier for a Winegard "batwing" crank up roof antenna, the amplifier is in the antenna head, not in the wall plate. The standard wall plate is simply a power injector that sends power to the rooftop amplifier.

Not the 12v power outlet. Sometimes the power unit will go bad. You can go on the roof, disconnect the coax from the antenna, and see if you're getting 12 volts up there to the amplifier. Using a voltmeter, put one probe on the inner wire and the other probe on the threaded connector for ground. If you're getting power to the roof and your signal doesn't change when you turn power on and off, then it's possible your amp has gone bad. Everybody wanna hear the truth, but everybody tell a lie.

oldjohnt Posted May 12, 2019 Report Share Posted May 12, 2019 I have owned BOTH those antennas where the amplifier is up inside the head, as well as indoor stand alone TV signal booster/amps. Obviously, it's easier to by pass the amp and troubleshoot if they are stand alone indoor units WELL DUH LOL although some are still nearly impossible to gain access and/or attach coax. One thing I've noticed is there's a difference when troubleshooting the batwing amplifier types if you A) Just turn OFF the 12 VDC power injector versus If you attach a new length of coax up on the roof to the batwing and run it direct down to the TV. When you run the direct coax you're obviously NOT injecting 12 VDC, same as if all is left in place and you just disable the power injector, but I have observed a noticeable difference in those two methods. Of course there can be coax or connection problem contributions. FWIW Again I found more often a coax or connection problem then bad amps. FWIW I switched to a King Jack and it outperforms a batwing BIG TIME A funny story this winter in Florida my buddy was having all sorts of problems with his coax from the antenna to TV. Mine was working perfect and I was able to receive 3 times as many stations and we BOTH had the same antennas. HOWEVER my old coax up on the roof was all ratty looking and had some outer shield exposed covered with caulking.

I have both a Jack and a Winegard Sensar IV (Batwing). The Jack works poorly for the VHF broadcast band and is about on par with the Batwing for the UHF band. If you have an older Batwing, there is an attachment available called the Wingman that improves the UHF reception.

oldjohnt Posted May 12, 2019 Report Share Posted May 12, 2019 To add one more testimonial, after me and another person bragged how many more stations we got with our King Jack (Both of us got far better reception) versus our Batwings, another buddy bought one yet his didn't work as well as HIS batwing lol. There's just a lot of variables and unknowns and different conditions. However when using Batwings when I added that extra 3 or 4 more element UHF upgrade, It helped very little ???????????

Dutch_12078 Posted May 12, 2019 Report Share Posted May 12, 2019 As the current FCC mandated channel repack progresses this year and next, more and more stations are moving to high and low VHF frequencies where the King and other UHF optimized antennas perform poorly. https://www.rabbitears.info/repackchannels.php Dutch 2001 GBM Landau 34' Class A F-53 Chassis, Triton V10, TST TPMS 2011 Toyota RAV4 4WD/Remco pump ReadyBrute Elite tow bar/brake system Link to comment Share on other sites More sharing options...
oldjohnt Posted May 13, 2019 Report Share Posted May 13, 2019 Fortunately, I still have a batwing on hand in addition to my currently installed King Jack which performs much better now, but if stations where I travel repack making the old batwing best in the future I WILL CHANGE BACK IN A HEARTBEAT LOL John T Link to comment Share on other sites More sharing options...

Tom_M Posted May 13, 2019 Report Share Posted May 13, 2019 Keep in mind that about 25% of TV stations are broadcasting on the VHF band. As far as I know the Winegard Batwing is the only RV antenna the does well for the VHF. The wide wings of the Batwing is the VHF portion of the antenna.

Thanks Big Jim, we have pretty well beat this subject to death, lots of good info from all the fine gents here. For a bit more boring reading and research take a look at these sites: The seven best RV Antennas https://www.outsidepursuits.com/best-rv-tv-antenna/ Amazon RV Antennas https://www.amazon.com/s?k=rv+television+antenna&hvadid=78340255731091&hvbmt=be&hvdev=c&hvqmt=e&tag=mh0b-20&ref=pd_sl_3h3q9my4s4_e Camping World RV Antennas https://www.campingworld.com/electronics/antennas?msclkid=8a325e396ffd13bc331402e0a3d43c7a&utm_source=bing&utm_medium=cpc&utm_campaign=B_S_NB_CW_Electronics%2BGPS%2BSatellites_All&utm_term=rv%20tv%20antenna&utm_content=Electronics%2BGPS%2BSatellites_Antennas Bing Search RV TV Antennas https://www.bing.com/search?q=RV+TV+antenna&src=IE-SearchBox&FORM=IESR3A&pc=EUPP_UE00 Based on my own personal experience and research its my conclusion the best antenna depends on six factors: 1) Your location 2) Your location 3) Your location 4) What (channels and frequency) are being broadcast in that area 5) What (channels and frequency) are being broadcast in that area 6) What (channels and frequency) are being broadcast in that area LOL It depends on stations near where you're located and what channels are being broadcast within your range. In some areas a person may receive more channels with one antenna while in another area a different antenna may yield more stations. Just because in the places I frequented the most in the last six months my current antenna yielded the most stations, doesn't mean in some other city a different antenna might not yield more. Your present antenna may be fine, a bit of troubleshooting, maybe check the coax and connections ?? verify your 12 VDC power injector is working and actually supplying voltage up to the antenna ?? and you may not need anything else. Do your homework, research what's (channels and frequencies etc) broadcast where you will be, look at the options in the above links, make a wise informed decision. If yours isn't able to be repaired, STUDY (look at reviews and research) THEN PICK THE ONE IN YOUR BUDGET THAT WORKS BEST FOR YOU IN WHATEVER LOCATION (OR LOCATIONS) YOU PLAN TO VISIT. Perhaps if you stay in one RV park an entire winter one antenna is best versus if you travel the entire USA another might be better ??? Hard to say with so many variables, different antenna designs and what's being broadcast within your range.

Tom_M Posted May 14, 2019 Report Share Posted May 14, 2019 SCVJeff who was a member on RV.NET did an extensive test of the Jack vs. Batwing. Jeff is a TV broadcast engineer and used a spectrum analyzer to compare the two.

oldjohnt Posted May 14, 2019 Report Share Posted May 14, 2019 WOW thanks Tom, that's almost too much information even for us techys lol. In the cities I was near last season my King Jack outperformed my Batwing substantially BUTTTTTTTTTTT I'm glad I kept my Batwing as I may be somewhere different next time (where it might out-perform my King) and they both mount and exchange so easy on the same mast.
