Thanks again GroundUrMast,
My old antenna (which doesnt rotate anymore) is something like this
http://www.antennacraft.net/Manuals/HDMS9100_Manual.pdf It worked well for me for about a decade before quitting but it would be nice to pull in a few more channels. If there is nothing like a good quality version of the Lava antennas, I guess I am back to either cobbling together antenna(s) with a rotor or filters or perhaps getting a new Antennacraft Ministate antenna.
P.S. the range of VHF signals I would like to recieve are about 106 degrees apart and UHF about 156 degrees apart so multiple antennas with filters is likely to be very costly as you suggested earlier.
