Astro 220 losing connection with collars

[Boom]

Hey there,
I have a 220 that will lose the dogs pretty much every time when they leave the road.
It has the long range antenna on it as do the collars. Is there anything I can do to solve this
Issue, or is it best to just send it in?
I know the collars are fine because they work perfect on my buddies astro.

Any advise or input would be much appreciated.

Thanks. Mike

If you havent updated your gps on the computer that would be the first thing I would do and update the collars as well...

[Boom]

Thanks, I'll give that a try

Sounds to me that your ant. connection is broke inside the 220 unit. Do a search and I'm sure you'll find some inf on it.
