Tower Guy is a TV station engineer with many years of experience solving reception problems.

As ADTech told you, he has been in on the design and testing of the DB8E from the start, because he works for the company that makes it. He has given expert antenna advice many hundreds of times, if not thousands of times, on at least four forums.

I am 81 years old and have been experimenting with antennas since I was eight years old, when I built my first crystal set radio. Since then, I have experimented with many ham radio antennas, antennas for analog TV, and for the past 6 years with antennas for digital TV.

How many "experts" do you need before you are at least willing to try our ideas?

Here's the point:

Your problem is not simple, as it would be if all your signals were in the same direction. We want to let you know about some of the problems that you will be faced with, and not raise your expectations only to have them crashed on the rocks of reality. It is a lesson we have learned the hard way, from people that have been disappointed by their results.

I am always amazed when someone wants a simple system that duplicates what a CATV system does with multiple antennas, amplifiers, and modulators costing thousands of dollars. You will need to cut back on your expectations and settle for improving one direction or be prepared to spend a lot of time and money building a system that does what you want.

Try one direction first, and see what you get.

We can't guarantee that our advice will work. We only have the information that you have given us so far. There might be other factors that you haven't told us, like trees and buildings in the signal path that the tvfool report doesn't take into consideration with its computer simulation.

I don't know your exact location, but I see a lot of trees in the general area NW of the center of Tobaccoville. See the attachments. Did I get close?

scroll down to Trees and UHF

You can use the interactive map feature of tvfool to show the green signal lines that will help you aim your antenna, and to see what might be in the way. An example is in the third attachment. Enter your information here:
