Hi Keith,

I also live in the country with a long driveway, and don't like
surprises.

I played with the various ones out there, built special antennas, and
none were reliable.

Then I discovered:

http://www.miltronics.com/driveway.php

It works precisely as advertised, zero range problems. Plug and play.

My receiver is mounted on the porch, and the receiver has a N.O. relay
which closes on trigger. I run that into an X10 transmit module to
inject a signal into the power line, beep the driveway beeper, turn on
all floodlights and start the video cameras in a scan sequence.

The only problem I have had is ants getting in and building nests,
causing false alarms. I solved this by cutting little pieces of No
Pest strips and tucking them around the battery. The electronics part
is sealed in silicone. The batt compartment has a door, and room for
some slivers of No Pest which I change every time I change the 9V
batt, which is about every year and a half.

Tech support is excellent and toll free.

I buy mine from www.shomer-tec.com but you probably can find other
sources. Shomer has been the cheapest and good service.

I think this may do your job. I'm running at least a thousand feet,
and in playing, the thing will trip the receiver in the barn, meaning
I have a significant fade margin.

Regards ... Steve
