Nedra E 5 out of 5 08.21.2014 at 4:53 pm I ordered this product in yellow, orange, green and pink. We had a puppy visiting who thought the dogs’ antennas were a fun toy to bite and PULL till it ripped apart. We have three (3) DC-30 collars and one (1) DC-40. The DC-30 replacement was easy to tell and do, and it was fast. My husband was doing the replacements and didn’t watch the YouTube video on How to replace the Garmin DC-40 antenna. So, he unscrewed too many things and then spent 2 hours putting those back together so he could do the simple antenna replacement. The antennas look great and work, and are actually quite easy to replace. The only thing I cannot tell you (yet) is if they have a greater range as indicated. We live in challenging topography, a hilly farm, so we can lose the dogs’ signals. We have 2 siblings who like to go on walkabouts and we’ve had to retrieve them with the Garmin and our pickup. Each time there were in locations we would NOT have known to look in had they not been wearing the Garmin DC-30 and DC-40 collars.
