Default Antennae Booster

h a spectrum analyzer and an RF sweep generator.

The rotor also has a bypass braid around it which many people
forget.


What is a bypass braid? I've never heard of the term. Neither
has Google search. Do you mean something like quad shielded
RG-6/u?

A large tree is going to hit by lightning first.


Large height or large girth?




Bypass braid for a rotator is for lightning protection. You put a piece
of wire to the mast above the rotator and then to the mast below the
rotator. That is suppose to make a good connection from the top mast to
the bottom mast.

It is not so much the actual gain of the amplifiers, but the noise
figure. If just feeding one or two tv sets all the gain needs to be is
just to make up for the loss of the feedline if the amp is very near the
antenna and a little more depending on the noise figure of the TV set.
If the amp is near the TV, it needs very little gain (maybe 10 db) and
better have a noise figure much lower than the TV tuner.

Hopefully a tall tree will get hit first,but no guarentee.
