Your poor horse (house - grin)

Might be worthwhile using leaky coax (radiates over its length - often
used in road tunnels and mines) or maybe working out an antenna
splitting exercise to various parts of the house. (ie two or more
antennas) Use 1/4 wave (or odd multiple) Q sections at each antenna and
combine them with a T connector before plugging into the TX. You will of
course get occasional nulls where two antennas patterns meet out of phase.

A "badly fed" antenna at one end of the house with the TX at the other
may radiate enough from the feedline to make the system usable. I am
talking about making a deliberate mismatch here that still looks like 50
ohms at the TX. My first thought here would be to use a 4:1 coax balun
at each end and use 300 ohm ribbon in the middle for maybe 30 feet. In
odd places I'd then spread the 300 ohm ribbon conductors apart so they
radiate a little more..

You may even find that placing the current good antenna in the roof
space might work better.

I have a small 1 watt transmitter. I have a simple goal of using it to
cover my horse so I can tune the same music throughout.

I have tried a variety of antennas to get it to work, but have been
largely unsuccessful. I guess I don't know what I'm doing!

My latest and best antenna is a j-pole I built with copper pipe and
mounted inside my garage. No matter where I place it in my house though
I am simply unable to create a quality signal that carries more than 50
feet.

If anyone is willing to give me some tips I'd be very appreciative.
