Hi David,

I would suggest that you look at the following website:   www.linearcorp.co=
m.
Linear is a major supplier of wireless relays. They also have remote
gate operators. So I think you should be able to find what you need
there. Also, they have just general duty wireless transmitters and
receivers that will work up to a few miles away. Do be careful however
of any restrictions you may have in your country about the use of
radio frequency devices.

By the way, how did you make out with your alarm system and your
special grounding requirements?  Are you still having problems with
the water buffaloes or were you able to contain them?   :-)

Here in the US our "varmints" are usually more docile and get no
bigger than a deer.
