    Ian - thanks for the offer, looks like it MAY be OK. I ought to take the boot liner out to double-check when I've a bit of time though...see what condition everything's in...

    * Need to get some silicone grease, I know...
    Never WD40 as you know and really not even silicon grease on the mast, just a good strong upwards clean with an alcohol based tissue and then throughly dried off with a clean tissue until spotless and dry.

    If it's still sticking and making a ratcheting noise then instal a new mast and perlon.

    I'm pretty sure I've got a brand new boxed one kicking around in the garage, I can bring it along on the Tour if want Martin??

    A new mast fixed that.

    Re-installing it, you have to be quick to run around the the back of the car to get the nylon tail to pick up! LHD would be easier...

    LHD is a tad easier, yes, but RHD is more fun to watch (for the spectators).

    LOL - I am NOT doing anything on the Tour then...knowing my luck there'll be 3 separate iPhone videos of the charade captured and shared for everyone (else's) entertainment...


    Clive - alcohol rub - OK, fair 'nuff...will hunt some down...somehow doubt the old vodka at the back of the cupboard is quite pure enough!

    I'll hold fire on a new mast while I try and tidy this one up - it's been absolutely fine for the last 7 years (20?), so fingers crossed...

    While I don't want missing the popcorn time for everyone watching the owner running around the car, if it suddenly failed with no apparent reason, I would look into it from the mechanical (bent mast with increased friction, damaged retractor nylon cable teeth) as well as intermittent electrical issue (corroded female terminal, water soaked motor, etc).

    On the mechanical side, if you powered up the audio head unit while at motorway cruising speed, eventually, your mast will be bent rearward and it will accumulate all sorts of debris such as road film, etc.
    Just wipe them off and carefully bend it back gently.
    Normally, this is enough to reduce the friction (if that was the cause of issue although normally, if the bent mast was the cause, it will stuck half way or at the very end of the travel and not like staying at max height) and fix the mechanical issues unless your retractor nylon cable teeth were damaged.


    For the electronics aspect, I believe you have non-JDM spec aerial/antenna (ANT) assy (without the half height option) so you only need checking 3 wires and you have just two positions to test, fully up or down.

    If you peel off the left side boot carpet where the ANT motor is mounted, there is a 4 pin non-WPC at the motor.
    You can test the ANT motor without running around the car…..

    I don't have the photo showing the wire colour of the ANT motor connector on UK models and only have the one for the JDM mating side so please keep this in mind when referring to the wire colour.
    It could be different for your model but if you have multimeter, easy to check.
    Having said this, the wire colour at the mating connector for GND (BLK) and switched +B (PNK/WHT) are the same for all country spec so the remaining wire is the +B on UK models as only 3 wires used instead of 4 on JDM.

    The 3 wires are; GND (BLK), +B (WHT/BLU, always at battery voltage regardless of IG key), switched +B (PNK/WHT, only becomes live when IG key in P1 or P2 AND audio head unit powered up).

    Please disconnect this 4pin non-WPC connector and test the ANT motor as a standalone parts.
    All you need is to keep power between the GND and +B terminals.
    While keeping power at these two terminals, if you apply 12V at the switched +B terminal (as if you powered up the audio head unit), your ANT should go fully up.
    As soon as you remove the switched +B, the ANT will go down.

    While in there, please carefully inspect the condition of the female terminals at the 4pin connector.
    Ideally, you want to use the mating terminal to feel the friction when inserted to the female side but you should be able to tell any corrosion, damages, etc by looking for the changes in the colour, loose/broken off metal parts, etc on the female terminal.




    Addition to the 4pin connector of the ANT motor, please check the female terminal of the 22pin connector located further forward behind the left boot carpet here.
    It's the big grey connector towards the right top corner of this photo.
    (Please ignore the black jumper wire connected to the GND point. It was used for other purpose.)


    This is very important especially if you have ever seen moisture at the back of the boot lid after driving the car for a while or if you have condensation inside the tail light assy.
    Several owners experienced different issues because of the damaged female terminals.

    Any damages to the female terminals here will cause ALB/TCS warning light for RR w/speed sensor (even if the sensor was fine), BRAKE LAMP warning light on the dash, ANT motor issue, etc.

    Honda should have used WPC type connector and not non-WPC.
    Same reason for the intermittent lock/un-lock switch at the door handle as Honda used non-WPC behind the door card where it can get moisture.


    Best of luck for the popcorn time.....

    If I'd had the intelligence to park the car on the other side of the drive and not use the ignition switch instead, that might have worked.

    But I don't and didn't, so I blindly followed orders...

    I'm off to buy a stupid German car....

    “I find myself irresistibly attracted to cars that nobody else buys. The NSX is a classic of the genre because nobody buys it and yet it’s a fantastic car. It’s got a wonderful compactness and simplicity and unpretentiousness to it. Honda rudely continues to make them whether we like it or not, even though there can be no commercial logic in doing so — I thoroughly admire that.” Rowan Atkinson

    I try and clean and lubricate mine at least once a year.
    I use "Tri-Flo" teflon lubricant.
    I have been using it on helicopter sliding doors for years on the track and teflon supports.
    Tri-Flo won't collect dirt and is the boll!cks for the helicopters.
    It was originally used for bicycle chain lube.
    A bit pricey but it works.

    Cheers
