Overview
The Garmin 010-10856-00 is a 2-pack replacement VHF antenna set for Garmin Alpha and Astro dog tracking and training gear, covering both the handheld unit and a DC 20 tracking collar.
The set includes two different antennas: one intended for the DC 20 collar and one intended for the handheld. The handheld antenna is used with compatible Alpha, Astro, and Astro 220 devices.
These are device-mounted antennas used by the tracking system and are not meant to connect to a fixed-mount marine VHF radio or any coax-fed antenna run on the boat.
Key features
- Two-antenna pack with one antenna for the DC 20 dog tracking collar and one antenna for the handheld unit
- Compatible handheld support for Alpha, Astro, and Astro 220 systems
- Replaces a missing or damaged tracking antenna without changing the rest of the handheld or collar setup
- Helps avoid mix-ups by keeping the correct antenna matched to the collar side and the handheld side of the system
What’s included
- Antenna for DC 20 dog tracking collar
- Antenna for Astro 200 handheld
Compatibility and fit
This set is meant for Garmin tracking systems that use a removable VHF antenna on the handheld and on a DC 20 collar. Confirm your collar model before ordering, since the collar antenna in this pack is specifically for the DC 20.
If you only need to replace one side of the system, keep in mind this pack covers both. The handheld antenna is the one used across compatible Alpha and Astro handheld units, while the other antenna is for the DC 20 collar.
Use and care around the marine environment
If you run your tracking gear on deck, in a tender, or anywhere it can see spray, keep the antenna connection area clean and dry after a wet day. A quick fresh-water wipe down and drying before stowing helps reduce salt buildup on the connector.
This set is a practical spare to keep in a console or gear bag for crews who rely on a Garmin Alpha or Astro handheld while working a shoreline, running shore trips, or spending time in remote areas with a dog on the move.
