Hey Guys,
I have a Question,
will a Discone Antenna work for FM broadcasts?

Hey Guys,
I have a Question,
will a Discone Antenna work for FM broadcasts?

I noticed the length of the Radials are only 2.5 inches over 1/4 wave for 99.9 FM. With the Top antenna (used for 50 mhz) is about 2 inches under 1/4 wave.

I would imagine it would work fine, but need some other thoughts on this.

look it up online and see what specs are. my guess is the swrs go up in the 3 meter band.

they are really tuned for tx on the 6-1.2ghz ham bands and the gain is like 0bi and less at that.

I asked an engineer friend of mine about it,
he said hell no.

So I just wound up ordering an actual 1/4 wave antenna.

Part 15 FM report to come hopefully by Monday
(I expect to be on by this weekend)

It seems to me that given the wavelength matching as far as size is concerned, it should work perfectly.

A quarter-wave FM discone would be a very handy small size.

My 1/4 Wave antenna arrived today!
(Not even 24 hours since I ordered it)
Now I'm just wondering where my new FM transmitter is. It was supposed to get here today, yet it was last reported in Florida.

All I know about discones is what I have read. If I recall correctly, they work for frequencies at and above the design frequency and are wide band because of this. If this is correct then a discone cut for 50 MHz should work for FM BCB.

Since you have it and will likely try it let us know what happens.
