I presently have a 25 year old directional VHF-UHF antenna on a rotor in the attic. It is attached to 622 but I am upgrading to 722k. My furthest station is about 50-60 miles. The reception isn't great with this antenna. Seems irratic on some channels. I'll have signal in 60's it will go for awhile then I will loose signal yet strength hasn't changed. I do not have any amps just RG6. Thought a new antenna may help. Would directional be best with the rotor? Amp help? Any suggestions appreciated.
