Commercial 403 MHz radiosonde antenna?

[Bryan Klofas]

Hey Everybody--

I'm planning on putting a radiosonde station up north, and need an
antenna that is a bit more rugged than my homemade 1/4 wave vertical
antennas. Temps down to -40C, winds 100 MPH, or something within those
ranges. Anybody know of a good source?

Laird used to make a 403 MHz 1/4 wave vertical, but now all I see is a
410 MHz version with some gain, not ideal. Their salespeople don't seem
to have S11 parameters, not encouraging.

Thanks!

Hi Bryan.

Take a look at https://amphenolprocom.com/

They are good quality, I've never had one break. 

Cheers

You can try one of these. I made several using various materials. Wire,copper tubing or heavy pieces of coax will make a very rigid and effective antenna. Just a thought.
