Hi Albert,

I presume by this "range" that the beagle moves unhindered WITHIN the
range of the antenna, and outside of this range she gets a shock (or
some form of behavior modification).

If that is accurate, then boosting range would accomplish your goal.
The problem I had was presuming that the antenna was at the perimeter,
and if your dog penetrated towards it, entering its field, that this
would "modify" her behavior. I am more familiar with antenna
perimeter fences were a collared pooch approaching such a fence would
be -um- stimulated.

Anyway, as you have already noted the design of the transmitter and
the antenna both, then you have options with both. Using the same
antenna, you could feed your transmitter into an unused stereo (or
monaural) amplifier and use that to drive the antenna with more power
(say 1 to 5 Watts). Then you could adjust the range with the volume
control. If this worked, you could then go out an buy a dedicated
audio amp kit ($10-$20) that fits this power range.

Another method is to replace the antenna with conductive stakes driven
into the ground. At this frequency, ground conduction has a fair
range. It was one method of communication that was used with trench
warfare during WWI. The further apart the stakes are, the better. I
would add that this comes with some shock hazard and is certainly not
within the warrantee of the product (but nothing suggested here will
be). As this a strictly an experimental long shot, try the simpler
suggestions above.
