Product Description

Increase the range of your Instant Fence. Add an extra 1/2 acre to your dog’s outside playpen!

For larger or uniquely shaped yards, this extra transmitter can expand your coverage. Large, overlapping circular fields create even more more room for your pet to exercise, play, and stay safe. Plus, it’s portable for vacations or other locations. Requires the use of Wireless Fence Receiver Collars (sold separately - see below).


The range of The PetSafe Wireless Dog Fence can be increased by using two or more transmitters.  This creates intersecting circles and the signal is canceled where the circles intersect. This allows your pet access to the entire area. One additional transmitter would create a boundary that is up to 180 feet wide and up to 330 feet long.


One additional transmitter would create a boundary that is up to 180 feet wide and up to 330 feet long. Includes Transmitter and AC Power Supply.

    Posted by on Jun 24th 2015

    After one month with it both Dogs.. (Walker Hound also) love it started at the normal setting but was too high am now on the lowest setting for both dogs and they stay ring in the yard.. I was out side one morning and a large Doe came out of the woods on to the road in front of the house.. the Dogs barked but never left the area or even tried... The Doe on the other hand just walked away...Dogs seem more relaxed also from before we moved here back then had a 6 foot fence......

    The second day of wearing the collar after two weeks training, my dog chewed through the collar! I bought a collar at walmart to replace it, had to drill holes for special transmitter.

  4. Works in a pinch 4 Star Review

    Posted by on Feb 11th 2013

    I have a wired fence system that has a break in the line. As it is winter I will have to wait until spring to try and find the break.
    I have had a wireless system for just such emergencies, but my system is about 15 years old, and the transmitter was acting erratically. I purchased just the transmitter now, and it is working fine. Jake is safe and sound in my yard again!

  5. The Best Way to Love your pets 4 Star Review

    Posted by on Dec 26th 2012

    I live in a rural area on a little over 3 acres. Fencing the entire area would be prohibitively expensive. Fencing a small part would negate the advantages of the big yard. I purchased 2 transmitters and 2 collars for my Cairn Terriers. I have one transmitter on one end of the house and one on the other end. This gives my pets almost 1/2 acre that they can play in. They quickly adapted to the correction. They know their allowed area and stay in it.

    One tip. If you do not get the 90+ radius you are expecting, make sure to "resync" the collars. This is well covered in the back of the manual and suggested in the trouble shooting steps. I mention this because it *will* work without the "sync", but not nearly as well. This does not appear to be a digital code, but a setting of the receive frequency at the collar. These units were replacements and I was very disappointed in their performance until I performed the "resync". After that they performed exactly as advertised.

  6. Works great 5 Star Review

    This is the best investment for some one with an open yard. The dog learned quickly! and we are all happy

  7. Highly Recommended 5 Star Review

    Posted by on Feb 20th 2012

    I originally purchased the wired fence and within 4 months started having problems. I have a Lab/Newfoundland mix and an Australian cattle dog. They use to charge the wired fence and break through. I was searching for another solution when I came across the Wireless Fence. I have had mine now for 2 years and absolutely love it. I am now planning on adding a second transmitter to extend it further. I highly recommend it.
