  2. Remove the collar strap.
  3. Remove the rubber cover from the VHF antenna-connector screw.
  4. Remove the VHF antenna-connector screw.

To attach your new VHF antenna to the collar:
  1. Attach the VHF antenna connector to the DC 40 with the VHF antenna-connector screw.
  2. Place the rubber cover over the VHF antenna-connector screw.
  3. Replace the collar strap.
  4. Connect the DC 40 to the collar using the mounting plate and the two mounting-plate screws.

The thing that sets this antenna apart from others is the built-in strain relief that matches the strain relief notches inside the collar unit. Others lack the strain relief allowing too much movement which ultimately causes metal fatigue and breakage. I discovered this the hard way (twice).

I would be happier if I had known you carried the tuff skin long range Garmin antenna. The replacement, as well as the original, has a design flaw that allows it to break at a weak point in the shaft of the antenna.

It is about 4" longer than my original and whips about, but works fine.
