Sorry to hear that but i know you'll see it as a challenge, which is good.

Have you ever tried a standard vertical antenna? Just usual rain fall 
tube and cheep loudspeaker cable and a 10m vertical on the top of the 
house will give you up to 20 dB signal improvement at the same power 
levels i guess.
I also decided to do my first transmissions with the new coil at 1W TX 
power, just to see what is possible :-)
