Take a look at this
thread. If it makes sense to you, great, let's talk some more. If it makes no sense or is something you choose not to consider, that's OK too.
If you want to consider pursuing the idea, the next step would be to go on a field trip with an antenna, a TV and a portable power source. Look for a hill top within a couple of miles or less that would offer a line of sight to your home. Check to see what the reception conditions are really like at higher elevations, then decide if seeking information re. right-of-way would make any sense at all.
Take a look at your current TVF report (the one that uses the current location and elevation of your existing antenna), the column "NM (dB)" will tell you what stations you have a reasonable shot at... If you have an unobstructed view (no trees or close in buildings) the DB-8 and a good TV tuner should be able to receive stations with NM's down around 0 to 3 dB. Below that, there simply isn't enough signal... and an amplifier would then be like a pump in a dry well.
