Garmin TT25 / T20 Standard VHF Replacement Antenna (18.5″)

Antennas take a beating. They get snagged, bent, kinked, and occasionally destroyed when a dog decides to curl up and chew on them. The good news is they’re user-replaceable in under five minutes. The Garmin Standard VHF Replacement Antenna is the factory original 18.5-inch flexible antenna for the Alpha TT25 and Alpha T20 collars. Two Phillips screws on the mounting plate, swap it out, back in the field. No tools you don’t already have in your vest. The VHF antenna handles the radio signal between the collar and your handheld. A damaged or missing antenna doesn’t just reduce range — it can drop the signal entirely. If your collar is showing weak signal, dropping out at distances it used to handle, or not connecting at all, the antenna is the first thing to check and replace. Also compatible with TT15, TT15X, TT10, T5, T5X, Astro DC50, and DC40 collars. Need more range in open country or big terrain? See the Long Range VHF Antenna (22.5″). Running a small breed where a shorter antenna makes sense? See the Compact VHF Antenna (14.5″). Keep a spare standard antenna in your truck bag, it’s low cost peace of mind when you need it.
