Hi Matt,
the most broadband VHF / UHF receiving antenna, quite easy to build,
is a discone antenna. Search the web for "discone", you will find what
you need.

Looking for a broadband scanner antenna for my attic. Would like 29-900Mhz
receive and TX on 150 & 450Mhz ranges. TX is not that important really.
Any suggestions?

Matt
