Good luck. I don't know what is inside the tube but whatever it is it is too
short. If there are several sections you may not be able to retune it.
Probably best to find an antenna that is made correctly for your frequency.

Subject: [Repeater-Builder] Retune a Ant
__ Before I try and re invent the wheel I thought I ask if anyone else has
already did this or even if it could be done.
I have a 48 in Ant made by Antenex 5DB uhf Base that I plan on using
on a repeater at 444.750 the actually ant is enclosed inside the fiberglass
tube.
The SWR Is High at 444.750 abut a 3 that would be ok in Most cases but not on
the Repeater which wants to see very little SWR To duplex properly.
So My thought is to get a Dremel cut and remove the tube from the bottom
then remove it and get the Bird Wattmeter and Cut or add if needed the end of
the rod to get the SWR Low as possible
Then put it back together using JB- Weld or some type of Fiberglass repair
kit.
Thanks
