I optimized the location of my antennas yesterday. Making sure the reception for The Game is flawless is highly motivating. My wife went to that shell of its former hobby electronics store self, Radio Shack, for an Antennacraft heavy duty tripod. The staff, now trained to sell iPhone accessories and r/c gizmos, expressed shock and incredulity at the idea of putting up an OTA antenna to wean off cable.
Back to optimization, I learned that TV Fool is not fully featured on Safari for Mac. The option to show lines pointing to each transmitter from the pinpoint marking antenna location is not present on Safari. This feature helps to avoid siting antenna that leads to pointing it in the direction of trees and creating multipath problems. As a result, WPMT faded in and out during the course of a day.
By using TV Fool on Firefox for Mac, I found a spot on my roof that had a clear shot to WPMT. That's where I installed the tripod right after work yesterday to beat the next ice storm.TV Fool Report
I have increased the signal strength to 84% and the signal quality is an absolutely stable 100%. I really like the Digitenna antennas. So, I had a browser problem all along. If you are a Mac person and prefer to virtually walk the roof to site your antenna through TV Fool, use Firefox.
Hopefully, this learning experience will save somebody several hours of frustration.
