Average Reviews:
(More customer reviews)In general I'm pleased with the build and performance of this antenna. It seems to be at least as well built as the locally available antennas that I looked at and it met my particular performance and price point. I was extremely pleased to find that it is manufactured in the USA.
The problem is that none of the included instructions are specific to this antenna. The first page is generic to all the Crossfire antennas. The second page, while useful for proper assembly of the feed dipole, still doesn't reflect this specific antenna. This matters because there is no good instruction as to where to mount the matching transformer and feed cable. The pictures don't match the antenna. What they show suggests mounting the transformer on the side of the boom with one of the feed wires almost touching the feed network and the other touching the boom. This is wrong. A steel mounting clip is included to attach the matching transformer to the boom but there is insufficient distance between the connection point and the next element for it to fit. I decided that the best way to mount the transformer is to not mount it at all but to simply let it hang from the terminals at a downward angle, supported on the bottom side by clamping the coax to the side of the corner reflector boom in a fashion similar to that shown in fig. 8 on the first instruction page. This clamp, oddly enough, isn't included in the box. I ended up having to take the antenna back down and rework the mounting of the matching transformer because my first attempt resulted in a weak output signal.
In general, it appears that the CM 3679 is a new or updated design that hasn't been entirely thought out. That said, I'm now currently receiving two beautiful looking digital channels that my old antenna wouldn't provide.
