DTVO-4(White)King Controls, Bloomington, Minn., manufacturer of the King-Dome and VuQube mobile satellite systems, introduces the JACK digital, over-the-air HDTV antenna for RVs. Covering the full digital spectrum for both UHF and VHF signals, the JACK offers improved reception of UHF signals where over 80% of the new digital local channels are broadcast. With a wider reception range, the JACK antenna is less directional than traditional RV antennas to simplify finding a signal and scanning for available channels. At just 12 1/2 inches long, 16 1/2 inches wide and 2 inches high, the JACK antenna is up to 70% smaller than competing products and offers less wind resistance when deployed or traveling. The amplified antenna includes an AC to DC power supply and can also be used with an existing wall mount or video switch supplied +12-volt antenna power switch for simple retrofit. Two different mounting brackets allow quick and easy installation on your existing RV antenna lift or a pole in just minutes without any special tools. MSRP: $49.95. The JACK antenna is available in the U.S. and Canada through King Controls’ extensive dealer network. For more information on the JACK antenna, the location of authorized King Controls dealers or to learn more about its entire product line,  call (800) 982-9920 or visit

    I’m re-thinking what I thought I knew before reading this. Thanks for a well written piece that breaks through the fog to present a clear picture on a fascinating subject. RV Covers

    We bought this Jack antenna replacement head for our motorhome last week. Where we were camping, we pulled in 2 stations with the batwing, and 4 stations once we put on the Jack. Then when we got home, we rescanned in our driveway for our normal 11 stations. What we noticed was that we could pull in all 11 stations without even having to raise the antenna mast at all! So in our test, the Jack worked better than the Wingard batwing we used to have. Thanks!

    Wow! Big improvement. If you have a motorhome, get the complete system and get rid of the banging on the roof while driving. If you have a trailer you could consider replacing just the head, but think you are missing some of the other very positive features.

    I more than doubled the number of stations received, but several former stronger stations were a little weaker (lower numbered channels, i.e. digital 7 and 12, but not 13, 10 is too close to judge.)

    If you are replacing the traditional Winegard batwing and it was installed the way mine was (Monaco), I mounted the base backward and then cut the indexing knob tab off inside so I could have the knob pointing the correct direction. This way all the previous installation holes were all covered except for several screw holes. To make sure no sealant was pushed into the area where it rotated I mounted it then sealed it with ample self leveling sealant over the flange, screws and on to the roof. Think King should make this an optional mounting method in that most people will be replacing old batwings.

    It is a great product. Don’t hesitate buying the complete system.
