Choosing antennas and gear

First off, I live in Gorham, Maine. The advice I received from http://www.hdtvantennalabs.com/ advised me to start out with a small UHF antenna (pictured) called the Winegard HD 4400 which I purchased here at http://www.solidsignal.com/. The price before shipping is 21.89, not a bad deal for free tv. The UHF antenna gets most of the local tv because after the digital transition, many of the vhf channels moved to UHF. However, there are two channels that are vhf that I did want to get and that is channel 8 and channel 10, PBS. To get these channels I purchased two Winegard YA 6713's from Amazon. The YA 6713 is what is called a Yagi antenna which is highly directional and because the PBS station, channel 10, is 38 miles away and is vhf, I had to have a separate antenna.
In order to connect the UHF to the VHF yage antenna, I purchased two Channel Master Jointennas. One for channel 8 and one for channel 10. I only installed the one for channel 10 because 8 actually came in fine with the UHF antenna.
