vlf antenna question
Hi all,
I have a wireless fence, which operates at 17 kilohertz. It is used to
create a wireless fence to keep our dog confined to area close to the
transmitter and works in conjunction with a shock collar (the receiver
is carried by the dog).
We haven't used it yet, but the literature suggests the range is
around 90 feet.
I found the transmitter schematic on the FCC website. The transmitter
is nothing more than generic audio amplifier chips fed with 17
kilohertz signals from what appears to be a PIC or ASIC device. The
antennas are large (8-9 inch) air wound coils that have MANY turns on
them.
I'd like to increase the range without spending much money-so I want
something quick and dirty::
If I disconnect one of the built in antennas, can I hook up the
transmitter to an external antenna consisting of many turns of wire
mounted in the basement (say a 5 or 10 foot diameter loop)?? Would
this give the transmitter more range, or would the range be the same
as the smaller loops that are built in?
Thanks,
A
