Channel Master JOINtenna - Combines Signals from 2 Digital HDTV Antennas, Two Inputs & One Output, Power Passing for Preamplifiers and Boosters,

The Channel Master CM-0500V2 JOINtenna TV Antenna Combiner is designed to combine VHF and UHF antennas for improved TV reception. According to the FAQ, this device allows both VHF and UHF to be combined on both inputs without blocking any frequency bands. However, customer experiences with this product vary. Some customers reported that it worked great when used with an indoor stick antenna and a garage attic antenna. They were able to receive channels from different towers without having to re-point the antenna. On the other hand, some customers were disappointed with the performance of the combiner. One customer mentioned that once connected, the signal was not strong enough to connect. Another customer found that the combiner did not work with two antennas and advised others not to waste their money on it. However, there were also customers who found a solution to improve the performance of the combiner. One customer added a GROWORD-5G LTE filter to each line and noted that it helped to clean up the signal. Another customer installed a 5G Phillips filter on the input of the combiner and was able to receive more channels than just using a basic splitter in a combiner configuration. Overall, the Channel Master CM-0500V2 JOINtenna TV Antenna Combiner has received mixed reviews from customers. While some have had success with it, others have experienced issues with weak signals or loss of channels. It may require additional measures such as filters to improve its performance.
