? Hello Dave
?
? I'd be interested to know more about your disc dipole experiment, size and materials etc?
? A Google search brought up nothing.

Subject: Re: [tinysa] Wideband antenna
A better option to the discone is the bicone.? Sure, it's larger, but behaves a bit more like the LP over frequency, but without the directionality.? For his purpose, the discone may serve as the best choice.? I can't imagine what the Schwartzbeck costs.? It's a professional antenna widely used in EMC measurements for radiated emissions.?
If he really wants bandwidth, build a disc dipole.? I recently built an ugly version.? It measured well at or (mostly) under 2:1 from 135 MHz through 3 GHz and the pattern is dipolish.? Off hand I am not aware of anyone marketing such an antenna.? Someone should!

I agree 100%, Dave.
At least if directionality is the goal.
Since the OP originally posted a vertical antenna, I presumed he wanted omni-directionality with flat gain over a large bandwidth.
And if that is the case, the discone is a better choice than his vertical or the log periodic antenna.
