Tv Broadcast signal`s

This is the answer given by the designer/builder; Hello Harry,

If I only look at the lower VHF part, I see frequencies from 55 to 88Mhz.
This is about 30MHZ.
For a peaked antenna you are actually stuck with a bandwidth of 2..Mhz.. 3 maybe 4 Mhz.

It is possible to design a normal yagi with a bandwidth of about 8mhz...
But of course this is already at the expense of the gain... and gain was just what you wanted I understand.

So.... it is possible.... but 'only' for a few channels.
So for example channels 2 and 3 or channels 5 and 6.

How do you see that?!

Mvg

Harry is correct. It would be difficult for a Yagi design to cover all channels 2 to 6. But a Yagi would give the best gain for just one channel.

The way that Winegard solved the problem is to use a log periodic design (LPDA). An LPDA can use a single boom with insulators and crossover wires or a double boom.

There is not a signal everywhere. I have experienced this here. In the attic, with a funke antenna that is intended for the Uhf and the transmitter tower is 30 km from Aalten (Holland) where I live. Mvg

Yes, how to aim your antenna is important, especially with a high gain antenna.
