These long-range antennas are heavier duty than the ones that originally come on the DC30 and DC40 collars. They have better range and come in many bright colors. These antennas are 20 inches long.

    This antenna has had a lot of thought put in it. It’s made out of a stainless steel whip cable with a highly visible low memory coating. With all the testing we have done this antenna complements or surpasses all other antennas out there for the dc30 and dc40 antennas. The antennas are also soldered and the ring terminals are heaver duty then other antennas we have seen.

    I ordered the 20″ version and have much better communication between my Astro and DC 40 than with the supplied Garmin antenna. It is also more flexible and with various color choices, more visible. The terminal connection at the 220 end is heavier duty. After testing the first one, I ordered one for my 2nd collar. The free shipping was received in two days. I have recommended this product to my hunting friends.
