Description Technical Specifications FAQ's & Support Docs

The Channel Master JOINtenna combines coaxial inputs from two individual outdoor TV antennas allowing for distribution of the two antennas on a single coaxial cable.

Channel Master JOINtenna is designed to simplify installations in which a user desires to receive television signals from two different transmitter locations/directions without the use of an Antenna Rotator. The JOINtenna is built for outdoor applications with an all-weather housing and has two coaxial inputs and a single coaxial output. The most common application for the JOINtenna is in the several locations across the United States where television reception is available from two DMA’s (Designated Market Area) otherwise known as “Local Markets”.

Typically most antennas are directional in nature making it very difficult if not impossible to receive signals from both locations with a single antenna. Channel Master's Antenna Rotator has served as a solution to this problem for many years and while it allows the user to only use one antenna, the installation and user experience can be more complicated. If looking to avoid the installation of an antenna rotator by using two antennas, the JOINtenna is the answer. Simply connect the output of two antennas to the two inputs on the JOINtenna and then connect the JOINtenna output to the residential/commercial coaxial cable network to be distributed to a single or multiple televisions.

In addition to it's antenna “Joining” capabilities, the JOINtenna is also equipped with a built-in LTE filter to eliminate cellular LTE signals from interfering with your TV signals.

Best by far December 5, 2017
Reviewer: SamJam from Rural  
This amplifier is by far the best quality on the market today. I like the switchable amplification, it lets me test out different antennas and locations. The LTE filter eliminated pixelization on my weak channels. I know cell towers are everywhere, I didn’t know they affected TV reception so much. Fine product Channelmaster, you do good work.

Reviewer: Nat from Vacaville, CA  
Excellent unit - it works!
The Channel Master JOINtenna allows me the combine two TV antenna signals into one.
With 2 TV antennas 6 feet above my roof and the Channel Master TV rotor system, I clearly receive 32 broadcast TV station from Sacramento CA area.

JOINtenna August 14, 2017
Reviewer: Casey from Fort Lauderdale, FL  
I upgraded to an ultratenna80 to clear up some reception issues with West Palm Beach stations to the North.  I still must have a small antenna pointed South to capture the Miami stations.  The Jointenna works better than a standard splitter, but there is still just enough loss of signal strength to make the Palm Beach channels hit-or-miss depending on wind, or weather conditions.  I will now move to an amplifier to see if i can overcome the signal loss introduced by the jointenna.

Reviewer: Anthony Stricklin from Arlington Texas  
It works just as advertised. I could not get my ABC affaliate. The only channel that I could not get perfectly. I connect as the instructions indicated and it has worked perfectly. Reception is great.
