[Elecraft] KXPA100 AMP and KXAT100 ATU pics and info

Oak Hills Research sells a similar BNC bulkhead connector that fits in a UHF hole.

BNC can handle roughly the same power as UHF. The max voltage on an Amphenol UHF connector is 600V. The max for BNC is 500V. A Type N connector can handle 1500V, so you can see how poor the UHF is for its size.
