less than 100' from the base I never use anything more than the whips which come with the base when I am using 1 base. If you are not interfacing to a wired comm system be sure to terminate the loop between the bases. You cannot connect them 4-wire, just connect with a single XLR A-A and set bases on RTS. If you want to use the WTA connect the link jacks with a short Cat5.
The receivers are on a table and I do need more than 100' of range. The Shure omni should be fine to get the antennas up above the crowd.
Interfacing to a wired system that will provide termination.
May or may not need the WTA option but would like to have it available.
Thanks Pete.
