KING knows how important it is for you to stay connected to the world on all your adventures. That’s why they’ve reinvented their KING Jack line with the latest technology to bring you the best directional over-the-air antenna available. Better signal for more free channels, updated sleek design, easy to use. With its high-tech yet simple design, the KING OA8300 Jack digital HDTV antenna provides greater performance than expected from such a compact over-the-air TV antenna. KING Jack is designed for exceptional performance for the demands of either RV or residential use (indoor or outdoor), with long-range signal acquisition. KING Jack’s wider reception area makes it easier to lock on to available TV signals. KING Jack is less directional than traditional TV antennas which provides more channels with less need to rotate the antenna; yet, it still provides powerful signal performance with a built-in amplifier powered through your coax using the included 110v power-injector. KING Jack delivers significantly improved performance for UHF signals where more than 80 percent of new DTV channels are broadcast while still providing great reception of existing VHF channels. KING Jack is up to 70 percent smaller than traditional TV antennas and offers less wind resistance; plus, it’s simple to install on your RV or in your home attic or roof.

Easy installation, great reception.I purchased this to replace the original antenna on my 1991 5th wheel camper. It bolted right up woithout issue, and operates just as the original (mechanically). The reception improvement is beyond measure. I get channels parked at my house that my old roof antenna doesn’t get (65 miles from source)
Perfect for head replacementRemoved old damaged head and replaced with new one. It fit and worked great!

Best Antenna Out There For The Money!I installed this on my camper 5 years ago. I routinely get 23 to 55 channels. All local networks as well as many others. I installed the same unit on the roof of my house, and get the same results. I will say it is not flawless, but does not pixelate like many of the others I have tried. This unit works better than the “Mini Spider” type I had on my 30 ft antenna tower. I cut the cable 3 years ago, and save myself $100/month. Do the math!

Lots of channelsI purchased this antenna for my camp a while back and I liked it so much I bought one for my home. So I just mounted it outside yesterday. And I’m going to cancel my cable bill. I love this antenna. It gets lots of channels.
Lost VHF gain/reception and most likely whyThe King Jack(KJ), is packaged very nicely and all parts were present. I installed it as a replacement to a RV Batwing(BW), only because the times we camped where cable connection was not available we usually were wishing for more channel coverage (Saturday college Football games). Installation in my case was a snap, simply remove the pins on the BW & aluminum arms, disconnect coax, pull BW off, place KJ with bracket install onto aluminum arms, reinstall pins and coax. Like most I ran a channel scan before and after; the score BW-47, KJ-42. However I went deeper then that I looked at each channel prior because on my TV, it will show a channel is there but with nothing but a message that states Low Signal. I had 5 weak signals with the BW, all were subchannels of the same channel X.x . Using the website NoCable.org for my zip code, I noticed that they were the only VHF channels in my area and also 55miles away. With the KJ it did not even find these channels at all. So I believe that the KJ probably has a higher gain in the UHF band then the BW and the BW beats the KJ in the VHF range. This is the reason that Winegard added the smaller radials (AKA Wingman) to the BW. I can’t go with that option due to mount location. That is why I only gave the KJ a 3 star. Too many variables, broad frequency range, transmission range from you the receiver, and mount location, makes it tuff to please all, in all locations.
Excellent batwing replacementI ordered the King Jack replacement for our RV as the ‘batwing’ was flapping a bit when on the road and leaving wear marks on the rubber roof. In addition we were receiving numerous pixelated channels. The King Jack installed quickly and simply. Our reception went from 66 channels from the batwing with 20 of those too pixelated to watch, to 75 channels with zero pixelated using the King Jack. Note; the batwing had three rubber feet on the bottom. Once the King was installed the aluminum antenna mounting arms now laid directly on the roof. I addressed this by removing two of the batwing rubber feet, drilling two 0.332” holes in the bottom of the lower mounting arm near the top and inserting the two rubber feet as a cushion between the aluminum arm and the rubber roof. I also discovered the assembly screws used on the King were ferrous and might eventually leave rust stains on the white roof so after I was sure it worked, I replaced the nine of them with #4 3/8” stainless and #8 1/2” stainless for the four screws used to attach the mounting bracket to the King.I used my existing power pack from the batwing to power the King. Thus making the replacement even easier. Since proper operation requires the antenna to be raised, I continue to use my clothes pin method to remind me to lower it before breaking camp. I keep a labeled clothes pin on the antenna crank and move it to the gear shifter whenever I raise the antenna.

Better than I expected!I am what we call a ” Full Timer”, meaning I live in my 34 ft. RV. I live about 35 miles from the nearest tv tower and some are over 40 miles. I used this antenna to replace my old Bat Wing that had the wing man attachment. Not only did it cut down on the amount of fine tuning required, I also went from 34 available channels to 47. I will be purchasing a second King Jack for my camper in the country, where I just can’t quite pull in any channels well enough to watch.
