KING OA8500 Jack HDTV Directional Over-the-Air Antenna with Mount and Signal Finder - White

Installed on class A motor home myself. Very good reception and was an excellent replacement for the 23 yo batwing. Recommend a few installation tips.If you are going to drill a new hole in the roof, use a 1/4” drill at least 10” long. ( Be sure to measure well your location both inside and outside before drilling.) After drilling the 1/4” hole all the way through to the inside. ( Check now that you have clearances for the sensor base. If you made a mistake, you’ve only got a 1/4” hole to plug.) Take your hole-saw and place it on the ceiling into the hole and mark around the saw. Take a razor knife and cut out the marked hole so when drilling from the inside you won’t snag the fabric or whatever you don’t want to tear up on the ceiling. Carefully use the hole-saw on the roof. Drill just enough to get the roof wood cut through. Stop an look for any wires. ( Move any out of the way.). Now you can complete the large hole from the inside. The rest of the installation in in the instructions.Have fun. Take your time.

On our first camping trip in our new-to-us motorhome, we noticed that the old TV antenna leaked around it's crank when it rained, which was especially bad because the crank was directly above my wife's seat! On our way home we hit a wind gust and then heard a lot of rattling around up on the roof. After stopping and making a hot climb up on the roof I discovered the old antenna and mount hanging on by only a very rotted out antenna wire. I cut it loose and drove home. Next day I ordered this antenna and a mounting plate to (as I told my wife) "fix the leak." Nice to say the leak is fixed and our new TV now gets a good signal. The only thing I did wrong with the install was to not test the antenna install "dry" before sealing it down with lap seal. Due to a poor antenna connector, it was totally dead on the first try, causing me to remove it (a sticky mess) and fix the wire. On the second try everything worked well. Perhaps we can give a real test on our next trip.

I can not express how pleased I am with this antenna!!!! Story: Just bought a camper in February. Brand New. It had come with a omni-directional TV/AM/FM antenna. It was sort of a mushroom shaped affair that would only receive about three TV channels in a major metropolitan city where I know there were dozens more. The radio reception was worse. I did my research and looked at countless reviews before buying this antenna. It seemed to be the highest rated antenna of it's type out there. Arrived in perfect shape with everything that was supposed to be included. My installation was different from others in that I was not retro fitting an old raise/swivel type antenna, so treated it as a new install. When I started removing the previous antenna, I noticed that the manufacturer did a really bad job with the RG-6 connectors. Loose connections, stingers (center conductor) WAY too long, kinked cables etc. So I thought I would attempt to clean up the bad install first and give the original antenna a second chance. No luck there. It was just as bad as before! Out came the old antenna and in went this one. The instructions are excellent and I had the new one up and running in about two hours total. I immediately got 65 (count 'em) 65 channels!!! When I fine tuned the directional knob a little, I got 67. Of course I Dicor 'ed the new unit very well. I also installed a separate radio antenna and that works well too. Forgot to mention that I did everything I could to make sure my receiving equipment wasn't the problem. If fact, the radio worked better with a coat hanger in it than it did with the original antenna, and the TV got about ten channels holding an inexpensive indoor antenna out the window of the camper. I am SO pleased with this antenna. Have not experienced any troubles as pointed out in some reviews.

You will need to lay down the base along with the intena at the same time connect the cable to the one that's all ready in the ceiling. And line it up. Use your caulking at the moment you have connected and put the black cable cord all the way thru to the inside with the plastic extension. Use the caulking underneath the base plate and then underneath the intena platform. Check to make sure that nothing is binding as you turns the intena from inside right,left.Screw it all down evenly all the way around.lay down the caulking that you ordered with it.leberaly over screws around the edges, corners and anywhere else that's needed. If it's warm out that's good. It will lay down better. Before you start. Cleaning and preping the area is good. If you're like me you will be wearing the caulking on your arms and clothes. I dress for the job.have fun.dont fall off.

I don't know why this wasn't standard equipment on the new RV. MUCH better than original. Remember to use a silicone sealant under and around perimeter if installed on RV roof or wall.

This is a great antenna. I replaced a Continu.us antenna that came on my brand new Coachmen. I love the Coachmen but not sure why they went with such a bad antenna. I got some of the channels in the area with 1 bar and basically tv dropped so often it was not watchable. After I installed the King Jack and turned it on I was surprised to say the least. I thought maybe 2 or 3 bars on my TV of signal strength, was hoping for yellow. I had full bars, from red right to green when I had the amplifier on. From poor to excellent. I had 2 bars with the amp off which is double of what I had with the old antenna with the amplifier on. The trailer I had before I had a Winegard sensor. It was in between this antenna and the Continu.us one in signal strength usually in the yellow. I am happy I bought the King Jack. I almost bought the Winegard as I was familiar with it but the new trailer had all black colored equipment on the roof. The Winegard only comes as a complete kit all in white. I would have had to buy the complete kit and then buy a replacement black head. No thanks. I made the right choice with the King Jack and could not be happier. Note, I have a permanent site and upgraded RVs and antennas but all tested from the same location. King Jack is by far the best, by far.
