getting additional channels at the cabin
 

This is the analysis at my cabin in Northern Minnesota

Last year I put up a 20' mast and mounted an old antenna I got for free. It has about a 12' boom and looks like the design for RCA antennas. It has quite a few missing or bent elements most of which are the larger elements. Much to my surprise I was able to find a position for the antenna that brought in both 12 and 9 with out having to move the antenna. I tried it in the direction of channels 11, 13 and 31 but didn't pick anything up.
I am thinking that my best bet to pick up some additional channels might be to get a highly directional UHF antenna and pointing it to the cluster of 3 channels at 260 degrees and combining that with the signal from my existing antenna.
This site has a lot of very large trees and I don't see getting the antenna much above 20'. I am looking for any recommendations on the feasibility of picking up these additional channels and what antenna you might recommend

1. Your TV Fool Report has a warning that it is only resolved to the block level. It may or may not be accurate. Use these instructions to prepare a more accurate report: http://forum.tvfool.com/showthread.php?t=14508 -- Your report may or may not change, but if it does that make make a great difference in the equipment you need. Prepare two reports. One at 20 feet (like your original) and another at 40 feet. [You may not go that high but the information is useful.]

2. Here are some of your translators. Your current chart suggests they are unlikely to be received but they may change with a new TV Fool Report for your location:

K29EB 29 Fox
K51KE 25 NBC/Weather/Me-TV
K35KH 35 CW/GetTV/ABC/Ind
K21HX 21 Fox/Local/Movies/Bulleti

3. What kind of antenna do you have? Take a picture and post it.

This is a seasonal cabin so it will be another month at least before I get back up there but this is what it looks like http://www.menards.com/main/electric...002-c-6295.htm
Here are the two plots you asked for
