We have also made a couple of short poles that fit the CB aerial sockets on the front. They’re quite ridged so not suitable for high speed (in a T25 ?) or off-road driving, just for fun when camping. Arils are fitted inside the poles so the CB radio should still work. 
More info and photos and a full write-up to follow soon.
In-use reviews.
Pros.
Quick to fit.
Internal arils so CB radio should still work
Cons.
Not suitable for high-speed (in a T25 ?), or off-road driving.
Quite ridged so need clearance if moving.
The arils are low-grade so the CB range will be limited.
