I like this antenna a lot also, in particular the 5 ft. model.
I have found it to be very usefull in problem installs, those like fiberglass vans
and soft top jeeps ect.
Back in the days when I was testing and replacing antennas each day in the mobil
I found myself always coming back to the Firestick 11.
With that said, It is in fact a CB antenna and yes it is great for a Export radio.
Problem with it being usefull for 10 meters, It is to long, and after removing the
screw thats as short as it will get.
Making it a longer antenna for the low side is easy!! just use a longer screw.
You could Butcher it up by unwinding some turns from the top after removing
the brass insert, However I believe better choices are available and some are from
Firestick..
I am sure others will give you some thoughts on Ham Sticks designed for 10 meters.
BTW, I found a antenna that works for me and it is a custom made Slingblade antenna
that I have been using for years. Very broad banded antenna and of course that means
it is also a low Q antenna..
I doubt that I will install a true amature radio in my mobil, however if I make it thru
another sunspot cycle then I might replace my 2950DX that was stolen
