Bill,
I got my T2/IRF-6 from you a little while ago and I am getting similar problems, I seem to have very bad RF range (less than 50 feet) and also "blank spots").

I was thinking of installing 2 antennas in my house and one outside (I control my system from outside as well).

So I have a couple of questions

1) What's the news on the RTI hi-gain antenna, as I assume this should fix my range problem?

2) If I was to extend my existing antenna using T-pieces, what cable should I use and what additional antennas should I purchase?

3) Could I install 3 antennas off the IRF-6, or is this going to cause me more problems?

Many thanks
