1 or 2 or even 3 or 4 NM(dB) , is not important in the Green and Yellow reception zones of the tvfool radar report and channel list.

1 , 2 , 3 , 4 , NM(dB) becomes important in the Red and Gray reception zones when the signal strength is very weak and you want the signal real bad.

And -You say- you will do what ever it takes to get it.

((And some reception situations , the only Tv stations to receive are very weak signal strength ones.))

As an example , looking at your Pending Applications Included Digital radar plot and channel list.

Let's say that you have to have , WCVW Real UHF channel 44 PBS that has a minus -6.1 NM(dB) signal strength and is 67.9 miles distant and has 2 edge path obstructions.

The reception is not reliable with the HD7698P antenna and a amplifier.

And stronger amplifier does not make the signal reliable.

However changing the antenna height to 90 feet in the tvfool report will make the signal strength minus -2.0 NM(dB) , and at -2.0 the reception will most likely be reliable.

Will you go to 90 feet to get??

____________________________________________________

At Very Low Signal Strengths.

The point of reference numbers for reception is ~ minus -8.0 ~ -10.0 NM(dB).

A few locations are getting reliable reception down to ~minus -12.0 ~ -15.0 NM(dB) , however it is the ->Exception<- not the rule.

___________________________________________________________

It is much better to start with reception in the Plus Numbers.

The Point of reference numbers at the Preferred Better Signal Strengths for Reliable Reception are ~ Plus +8.0 NM(dB) ~ +10.0 NM(dB).

The trees and reception.

If you get the antenna up as high as you can reasonably get it.

By actually putting some real thought and effort in to it then your reception will most likely be reliable down the Pending Applications Included Digital Channel List to at least , WDCW UHF channel 50 The CW.

It is best to keep the front of the antenna in the direction of reception if you are installing the antenna above the roof , as far away from the trees in the direction of reception as possible and also have the antenna up high as possible.

The idea is to try and clear the tops of the trees or get as close as reasonable antenna height to clear the trees.

With out doing a any crazy monkey swinging and falling off the roof.

There are math formulas about angles and distance and etc.

The math formulas are not really helpful.

It is better to get up on the roof with some binoculars look into the distance and use your own evaluation and judgement.

As a ->Test<- , You can also , lay the antenna on top of a chimney of even put a chair on the top of the peak of the roof , 2 legs on one side of the peak and 2 legs on the other side of the peak of the roof , lay the antenna on the seat of the chair , aim the antenna at the Tv stations to the north east , connect one tv in the house and see what is received.

_______________

I make the Point about the trees because many people place little to zero importance concerning the trees reducing reception , the person has the antenna 1 foot away from and aimed directly into a big fat dense tree , and then can not figure out why the reception is not good.

After all is said and many points and evaluations are made.

-->The Only Way<--> to find out<-- is put a antenna up in the air and see what happens.
