    My GUIV with mast fully extended, there are 5 telescopic sections. At full extension (controlled by the rope engagement with antenna motor drive unit), by hand, I can lower/raise and rotate each section independently of each other. The fully extended travel is limited by the rope position/engagement with motor unit. IMO the 5th(bottom section) should have a plain end that allow it to be removed from body assy and the other top sections have a circumferential rolled lip that locates with and lifts the subsequent lower sub section as mast is extended.

    Think your bottom section may be damaged / deformed, allows it to be rotated but not lifted to facilitate removal from antenna body.

    Interested in what you find when pulled apart. Maybe drill a hole thru the sidewalls of the remaining stuck section, feed a piece of wire thru and try and pull it out of body sub assy on the bench.

    Whilst you have the complete assy out, check the snorkel bolts for tightness and if you have not already, U could seal up the snorkel entry joint thru the guard if water ingress is a concern. Give it a general clean as well.

    The bottom piece is definintely part of the mast.
    I have decided to remove the unit completely and pull it apart. A good excuse to do a clean up around the guard as well.
    There was a comment I found somewhere on google that mentioned a flanged bottom that required disassembly. They then had to flange the replacement mast.
    I will take pics and post up the result.
    No worries, that makes sense.

    Because the 'rope' is plastic but the antenna has to make electrical contact for the signal wire (centre coax) but be insulated from body there is a contact sleeve in the antenna assy that the bottom section slides thru.
    I was just making sure you weren't trying to pull that out... it's been a few years since I did one.

    It's like the 70's all over again.
    I was sick of breaking antennas all the time, so I might get a universal
    cb style antenna great reception and not breaking them all the time
    just use a uhf connector. think I will go this way a lot cheaper imo
    Will talk with my mrchanic and see what he says

    DO you think a decent UHF antenna would work,
    they appear stronger than a CB style antenna
    thinking one of the silver base loaded might work as weii
    decisions decisisions

    UHF uses fm frequency but in a different range I believe. So you should be able to use a UHF antenna without interfering with reception.

    I decided I needed to follow through on this project and so I set about removing the antenna unit from inside the guard.
    Everything was going much easier than anticipated and that should have been my warning.
    1 rusted, burred screw that is flush with the unit body stopped me dead.
    By now it was getting dark and so I pushed everything back up into the recess and will set about extracting the screw tomorrow.

    FM Broadcast Band is VHF band II ( 88 to 108 Mhz)... UHF CB is UHF band (477 MHZ).

    Because you aren't txing on FM only listening almost anything including the coax itself will act as an antenna... a metal whip, a length of copper glued to the window, coat hanger shaped to look like Oz etc etc

    Same thing works for CB as long as you don't transmit... tx and then the smoke appears if the swr is really bad or at best the signal goes 5 feet

    Pulled the unit apart this morning.
    Used the dremel to cut a slot in the rusty, stripped screw.

    Found 100 mm of rope wrapped around the centre.

    ant2.JPG

    All back together now but with the guard cover still loose, just in case.

    Now I just have to thread the new cable and mast in.
    Arms aren't long enough and I am not fast enough to do it solo.
    Will wait for wife to return and then 'fingers crossed' it will be done.
