The SportDog Dog Fence Transmitter is for the SportDog Dog Fence Model SDF-100. If you need to replace your SportDog Dog Fence Transmitter the part number for this dog fence transmitter (found on the back) is RF-104-S. Includes Transmitter and AC Power Supply. On June 7, 2010 the look of the SportDog Transmitter was changed. This new transmitter will work with all SportDog Underground Dog Fences.

We ordered this box to replace our weaker one after the boundary wire was broken. And I believed, wrongly, that I repaired the wire. There was another break. The 100a transmitter does alow for a wider correction zone and longer wire. I am pleased with this product.

We enclose around 15 acres for our 5 dogs and unlike other transmitters that advertised 25 acre coverage this one does the job.

Easy installation and set up. Enclosed four acres and used 14 guage wire. Running coincident with a cattle electric fence and no interference. Great.

We were happy to find this as my son moved with is 2 dogs to a house that already had the undergroundf fence. We already had the Sportdog fence and 4 collars(my 2 dogs also) at our house. We thought why not just buy the transmitter so we can still use our collars and if we take our dogs to his house we just bring our collars along with. When we contacted Sportdog, they don't sell the transmitter separately. Why would I want to buy a whole kit for $239.00. Doesn't make sense to me!

I really love my new fence transmitter. I like the sleeker design. I had to replace an old RF-104 model. Tried other fencers and finally bought this one. I have not bought any since I purchased this one. Finally, I feel secure that my dogs will stay in their yard. Also, another nice feature is the expansion size I can go to if I want to in the future.
