slot antenna

Oguzhan Kayhan

Hello all,
I'm planning to install first 3cm beacon at KM69 which will be the first in TA.

I already made the beacon side with vhfdesign's pll kit and a 2w PA. 
Now all I need is an antenna.
I already have a sma/wg adapter and built a horn but I'd like to use a slot antenna for better coverage instead of high directivity.
I'd be glad if somebody can share a surplus slot antenna if  left somewhere in the shack.
I know there are some amateurs building and selling them already but i'm a little tight with budget.
Any help would be appreciated

Best Regards
