Which antenna would work?

[Brentvsmaximvs]

I live in Somerset, Kentucky at the southern end of Pulaski County. What I pick up are stations from Knoxville, but I'd like to be able to pick up a few from Lexington.

I have a cheap antenna I ordered from tiger direct - its on a 20 foot pole. I'm wondering if 5 feet more would do the trick?

Any suggestions - my tvfool report is below
thanks
:D

The report you've posted suggests that you may have access to some Lexington market signals, but the report is flagged as imprecise. Please review this guide: http://forum.tvfool.com/showthread.php?t=14508 then add links for reports for your exact location, based on the current antenna height above ground, 25' AGL and 50' AGL.

Also, can you provide the make & model of your existing antenna? And, do you have a clear view toward Lexington or do you have to aim through trees?

Thanks

Here's my signal analysis - I have a somewhat clear view to Lexington. There are a few hills close by - but it surprises me I'm able to get Knoxville as there are lots of hills to the south east.

My antenna is a Digiwave ANT7287 Super DB8 Adjustable Multidirectional HDTV Antenna from Tiger Direct. I ordered it because it came highly reccomended. I appreciate your help and the signals I do get are really clear.
