Military Bands

Hi guys,

Can someone tell me where military bands are found?
I am going to buy a frequency specific cut antenna so please let me know what you think.

Yes - for Airband use.

Officially 225.00 - 399.95, but assuming you're looking for something a bit more specific as to where most of the traffic is found then maybe M0ls or one of the other forum sages could suggest how long to get it for the best results?

Buy a discone is my favourite, but it's such a big band that an antenna cut to a specific frequency might not be that useful. Do you need to listen to just one location - like a local air base or something? Discones and the other wide band antennas don't have any magical performance apart from being ok everywhere - which a dipole, cut to the right frequency, for example - isn't!

The traffic is 'spread' according to bizarre algorithms known only to NATO :-)

230.0 to 399.9 is the full extent.

Some sub-bands are used to other purposes:
There are multiple short military satellite bands.
328.6 - 335.4 Airport Glideslope transmissions.
380-385 Airwave TETRA mobile.
390-395 Airwave TETRA base.

The lowest freq used in the UK is 231.425
Not much above 385 MHz
There are quite a few large blocks which appear unused, but may just be un-obvious transmissions.
I reserve the right to ignore people who have made no attempt to the read the manual, and expect others to do it for them.

Are transmissions from land training areas encrypted do you know Minus? They would make for some very interesting listening!

Some aren't, but not being near to one I can't can't say what you can't get that might only be visible on an SDR!
