reception question

[lorens]

I can receive channel 49.1 kpdx perfectly, I get 22.1-3 when the sun is up. I also get 5 and 14 but not good enough to use. I have a vhf/uhf yagi roof top sighted to 145 degrees, I have a preamp at the antenna to boost signal strenght. Any clues as to why I can't get the rest which apper to be stronger stations.

The transmitters at the top of the list are Weak , and as go down the list , have less and less power. Make two new tvfool radar reports , antenna heights of 40 feet and 60 feet. For stronger reception.

...It appears that your "VHF/UHF Yagi" antenna is actually UHF-only. Otherwise, you would not receive UHF KPDX while not receiving 20 dB stronger VHF KGW and the other VHF stations in your radar plot.

Do you know the make and model number of your antenna?
