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.

Two antennae into one February 11, 2019
Reviewer: Doug from Vonore, TN  
One antenna having trouble pulling in some stations from 40 miles away.  Added another small antenna and joined it with JOINtenna.  BIG IMPROVEMENT.  Highly recommended.

Worked Well, but February 11, 2019
Reviewer: O. Duncan from Indiana  
This unit worked well for combining my two wire antennas. I was able to get all my local available channels  clearly. Just a bit of info though, this unit will not work with powered or rotating antennas that recieve power through the coaxial cable. I would recommend this product.

JOINtenna works well October 11, 2018
Reviewer: Anonymous Person from Baltimore, MD  
With Baltimore (4 miles) and Washington DC (40 miles) in opposite directions and with one antenna, DC stations were essentially unavailable.  Aiming a second antenna at DC and combining through the JOINtenna gives me over 25 DC channels.  I earlier had tried using a passive splitter as a combiner but got nothing.  JOINtenna is well worth the money.

Immediate difference. May 22, 2018
Reviewer: Gary from Cincinnati, OH  
Hooked up two antennas and ran a scan. Saw a immediate difference especially on channels such as ME TV and Heroes and Icons that show older programs, there was a marked improvement in clarity and quality. I have had no problems with the two antennas working together. Very pleased with this product.
