SHF

For those who like to experiment at higher frequencies this new product of Roberto Zech, DG0VE might interest you.

The TRV10G is a all mode 70cm to 3cm transvertor that comes in 3 flavors: 250mW, 2 Watt and 4 Watt output.
It's in a metalbox, thus not waterproof, and it has an SMA output.
So you'll still need some semi-rigid coax to get to your antenna, but that's true for most Ham-projects at this frequency.

It works from 10368 up to 10370MHz but it's true range is 10350 up to 10480MHz, maximum 500mW drive power.
