I have three modulators each with a different antenna that I made out of lamp cord cut to the frequency of the desired channel (Shango66 has a great how to video about this on youtube), each one from inside on the second floor can be received at least to the edges of the lawn, and the best one one can be received about a block in each direction.
I try and limit the range to less than that and use channels that I can't find any DTV carriers on so I don't tick anyone off....Though I've been wanting to design an RF booster based on spare sweep tubes and try to see how many miles I can cover as a pirate station on the holidays and whenever.

That is what I was thinking too, is that each modulator will stumble over the other, or damage each other trying to force though a splitter to a single antenna.
I have an old 4-Tube Sweep amp, runs on 4 6LQ6 tubes. I bet I could re-tune it to work on the real low VHF bands and give up some power if I felt creative.
I looked over frequency charts before I picked open channels I could potentially use on VHF. Channel 8 was always open in the Analog days here, and Channel 13. I don't think there is much from 2 to 13 in this area, but to be safe I use 13. Seems to give the best results. In the analog days, it was WREX from Rockford, which, even on a big bream antenna aimed at Rockford, it never came in well here, so even if it's DTV signal is sitting there, I am not bothering anyone.
