UHF Batwing recieve antenna

[Jim Sofonia]

I have UHF stations to the East, and others (mostly repeater stations) to the West. I'm thinking about building a batwing antenna that would be optimized for 470-608. Any ideas on this project? I would think the bi-directional would serve my location well. Where could I get plans for this?

It looks like what I had in mind. Do you have a link to additional info and the freq. it covers?

No links just calculations.

Center frequency is 540 MHz with a Q of 3.6.

BW = Fc/Q = ~ 150 Mhz; 1/2 BW ~ = 75 MHz. Low frequency edge = 540 - 75 MHz = 465 MHz;
High freuency edge = 540 Mz + 75 MHz = 615 MHz.

So it should cover 465 MHz to 615 MHz.
