Looks more like a dual band 2m/440 antenna to me, which is useful with an 857d. Maybe add a 10m antenna on the other side? Or a small screwdriver if you want multi-hf-bands while mobile (not as useful for a technician)?
It's a Pulse/Larsen NMO- [27/30/34] B-TLM, missing the ball at the tip. I sold and installed hundreds in the 1980s.
Well if he is thinking about bands other than 10M mobile, I'm not sure where a TECH would transmit, other than 10M...Of course he can advance, but I can't see putting those kind of bucks out, on an unsure amateur radio future...
Techs have HF privileges on 80, 40 and 15m as well (Morse only). Mobile CW is a blast!
Realistically, on the road, something with a SS whip will be the best choice. Anything else tends to be destroyed when it strikes stuff on the road.
What in the name of all common sense would a TECH know about code
Obliviously, it depends on the individual. As strange as it may seem to you, there may be some who actually like and use Morse. Speaking for myself, as a Novice, I found it to be fun. After upgrading, I again found it FUN to operate Morse while mobile... DXing and contesting included. Now, back to CQ WW WPX CW.
