DB4e with the reflectors removed. (ADTech, is that easy to do?)
Yep, if you've got a drill and a nice, sharp 3/16" bit to drill out the aluminum rivets. Reassembly, if required, can be done with standard #10 screws and nuts from your local hardware store.

I often recommended this approach when dealing with UHF stations that are in nearly opposite directions and are not of too great a power differential. You'll have HPBW of 40-60+° in each direction, depending on frequency.

The newest versions of our C2 and C4 now feature reflectors that simply clip into the rear loop base. It's really easy to just leave them off and get a bidirectional UHF antenna. The reflector-less C2 would have a bidirectional HPBW of ~70° and the reflector-less C4 would be between 30 and 45° depending on frequency.

Keep in mind that removing the reflector will reduce forward gain by 1.5-3 dB and *may* open up the door to multipath. No free lunch, you know.
