Does anyone sell a wireless pet fence that has a range of over 180 feet?

Question

petsafe is the only one i can find, and you have to purchase additional 180 ft. transmitters . I would prefer one transmitter that will cover about a 300 ft area.

Answer 1

I did a google on wireless pet fences and quite a few links came up, of course most were Petsafe. There were two other companies mentioned Innotek and Tri-tronic. The link below is from the Innotek system. I really don't know much about what you are looking for so you can check it out to see if it's what you want.
