You are naming tv stations that are in the directions of , York/Harrisburg and Baltimore. When selecting Tv stations you will like to receive use the Tv station call sign and the Real digital channel number. Read and understand about , REAL Digital Broadcast Tv Channels , Virtual Digital Broadcast Tv Channels , Analog Broadcast Tv Channels ,
http://forum.tvfool.com/showthread.php?t=695 . For the York/Harrisburg network Tv stations/channels the cost will be about 300 dollars , for the Baltimore network Tv stations/channels the cost will be about 300 dollars. GUM suggests 'must haves' but he is not telling you the whole story , if your 'must haves' are tv stations that are York/Harrisburg and Baltimore then you will need 2 Tv antennas , one pointed at York/Harrisburg and one pointed at Baltimore or one antenna and a rotor. A rotor does not work well with 2 or more Tv's because of the conflict with other Tv watchers that will develop over where the Tv antenna is pointed. What he is also not telling you is that if a Tv antenna is pointed at say Baltimore as an example , and you say that you will only like to receive say 4 channels , you Will Receive the other channels in the direction Baltimore because the Tv antenna is pointed at Baltimore. And this same situation is also true if the Tv antenna is pointed at York/Harrisburg. When GUM does this 'must have' 'don't care about' thing it causes a lot of , confusion , frustration , disapointment and even anger. . You can install one Tv antenna and Tv antenna mount and Tv antenna amplifier and coax now and point the antenna at York/Harrisburg or Baltimore. What will you choose for now?? So I can recommend the correct Tv antenna and ect.. . You can ad a second antenna later pointed in the other direction.
