Ok I have given your reception situation more thought then a sane person would and this is what I suggest. 2 antennas , a AntennaCraft CS600 with the HDP269 preamp aimed at about 316 degree magnetic compass mounted in a fixed position not on the rotor , for the reception of real VHF channels 4 , 13 , 10. For the real UHF channels I recommend a AntennasDirect 91XG UHF antenna with a

Separate coax cables will go from each antenna and amplifier to a 'UVSJ' = UHF/VHF Separator Joiner that is located in the house close to the Tv. The 91XG antenna and KT-200-COAX amplifier will be connected to the UHF input of the UVSJ. The CS600 VHF antenna and HDP269 preamp will be connected to the VHF input of the UVSJ. The output of the UVSJ will be connected to the Tv. This set up will deliver steady strong signals to the Tv.
