Driving along yesterday in gusty conditions, I heard a loud clunk on the roof of my car (Honda Civic 9th gen) as I passed a row of oak trees. Got home to discover the cover of the shark fin antenna was missing leaving the circuitry exposed. I returned to the scene of the crime and, despite a thorough inspection of the ditches and hedges on both sides, could not find the missing article. I can only suppose it was partly dislodged by the impact and blew off somewhere further along the road.

Called in to the local Honda dealership to enquire if a replacement cover was a possibility – no, the whole assembly has to be replaced requiring the headliner to be removed, and that would be £480, madam.

A quick trawl of owners’ forums reveals that this is not that uncommon, the wretched things can be broken off simply when washing the car and the only effective long term solution is to replace the whole antenna. The cover is attached by screws up through the base – the cover itself is just ordinary plastic and so becomes a bit fragile with age and exposure to the elements.

I found a Youtube video showing how to fit it but I do not think myself competent to have a go - grab handles, light cover, pillar trim etc all have to be removed with considerable potential for breaking something.

So the car is booked into my ever-obliging indy a month hence – the manager is going to do it himself and reckons two hours’ labour at £60 per hour, plus around £190 for the part. Has to be done and it’s a sensible price compared to the dealership quote. Just means driving around with plastic taped over the circuitry for the time being.

So annoying to have to fork out on something peripheral like this. though.

Sadly , the cost of parts for modern day cars has gone through the roof . Led headlights are easily £1k plus per side . A friend’s daughter has a 2015 Corsa with the wiper linkage worn out . Only £340 . The list goes on .

Makes the £180 odd quote for replacing my old Mazda3's front fog lamp seem comparatively cheap! And I thought that was a rip-off. Annoyingly for me the only thing wrong with it is a cracked and now holed lens. The light still works fine after 17 years and using the original bulb.

Oh to wish for the days that you could replace a standardised lens with another for buttons...

Sharkfin is "Car Aerial 7.0" on the evolutionary scale, which started with the cheapo 1.0 model from Halfords with the metal key to release the retracted aerial from its base. 2.0 was fitted into or alongside the driver's A pillar and could be raised or lowered by hand from the driver's seat, revealing to diehard drivers of BL products that, yes, this Japanese car had a radio as STANDARD. (Austin Rover soon cottoned on!) 3.0 - electric with a raise/lower switch; 4.0 - electric, automatic with radio - often to be found on a Jag exiting the golf course car park. 5.0 hidden away inside the bodywork, connected to the heated rear window element - or bootlid (Ford Orion). 6.0 was the universal roof-mounted number set at 45 degrees at the front or rear of the roof, the one that suddenly every single car on the road seemed to have, all with the same screw thread. Forever being left on and snapped in the car wash or nicked when the driver forgot to remove it, which was a total pain. 6.5 was the short-lived answer to theft and fragility of 6.0, a solid rubber 6" long indestructible aerial, truly functional yet hideous.
Any guesses to what form Car Aerial 8.0 will take? My car is finned, but I'd happily go back to 3, 4 or 5!

The side marker lenses on the 10th gen Civic, which are dreadful quality and let in water, are £120 each. It’s disgusting really.

I think I have got off quite lightly - what looks like the pretty much the same fin for the Honda CR-V is priced at well over £400. Utterly ridiculous.

I am thankful the car doesn't have LED headlights though I think the headlight lenses (if that;s the correct term) may soon need some attention with Meguiar's polish and sealant as they do appear to have deteriorated over the past year and I am going to have to put in some better lamps/bulbs as the current ones are truly pathetic. The DRLs are LED of course, so I cross my fingers they won't need replacing.. Pretty poor though - my old car, a Mk1 Focus, still had crystal clear lenses at 15 years old..

There are a few second hand aerials on free bay for around £50 . May be worth a punt

The helpful young chap at Honda did suggest this when he came round the corner to look at my stricken car, even scrolled through a few on his phone to show me! I came to the conclusion that it made little difference since I was going to have to pay someone to install it and I might as well have a new one that has not been subject to envrionmental stresses and is matched to my car's paint.. If the car was older and worth sub-£2k then that's what I would be going for and just blend it in with some touch up paint or go with a deliberate contrast.

Replaced mine (sun rotted) with old bicycle reflectors off the campus scrap bicycle pile. (technical theft. deportation is just around the corner) Considered bicycle LED tail lights but would have been a bit harder to fit and I doubt I would have been able to re-purpose the LEDs, due to the circuitry being tiny and me not understanding it.

(Arguably if you don't understand a bicycle tail light you should steer well clear of electronics)

Kept the original incandescent lights but one of these has failed so I may try LED's in it later this morning.

Fixing the lights seemed to go OK as horrible lashups go, replacing dead power and earth wires and using a connector strip with small LED's (I think 3.3V 5ma) in series with a 200 ohm resistor, in the bike reflector wing light

LED substitution didn't seem to affect the flash rate

Originally too much off-topic detail here so I've moved it to the original dedicated thread. Apologies, was posting tired. Mosquito kept me awake.

I have seen apparently "ready to go" aftermarket LED sidelights which weren't much more than a bike tail light in one of the all-night-hardware stores that are a curious feature of Taiwan cities, and thought "must remember that for if my sidelights fail"

Never seen them again, and I've looked.

This comment is gold.. having great flashbacks!

Mildly embarrassed to admit that I didn't realise these things were radio aerials. I thought they were some cod-cool boundary layer aerodynamics affectation (though I suppose they could still be that as well)

Always good to learn more about how new cars suck.

Looks like it's a common problem.

You would think that pattern replacement covers would be available - 3D printed maybe?

It's a poor design. Better to use the wire in the rear window heater. Cleaner more aerodynamic.

Honda Civic - Shark Fin Antennas - Something to Avoid? - edlithgow

Cleaner more aerodynamic.

Allegedly not. Generates corrective lateral force on cornering and oversteer, I suppose operating a bit like a sailboat keel.

One would think these effects would be tiny on a road car with a tiny fin, but, again allegedly, there are other road-relevant advantages on some road cars that I havn't readup on.

That was originally the Captain Quint "I'll never put on a life jacket again" clip from Jaws, but it seems to have morphed.

Its the Internyet, y'know? Virtually nailing a virtual jelly to a virtual tree.

Bit like fixing my wiring loom.

Aerodynamic stability advantages on hatchbacks. Looks like "You are going to need a bigger boat...er...aerial"

Cant be a new thing on race cars though. I had some slippery-looking 60's Corgi touring car models (Jaguar? Lotus?) with quite big fins behind the cockpit, though those were necessarily offset to one side.

Sad that a bent coat hanger will no longer suffice. Yet another example of automotive design costing a fortune to repair when damaged. Perhaps cover the exposed electronics with a suitably shaped oblong peice of plastic and glue it to the roof. It could perhaps be fashioned from one of the many differently shaped containers found on supermarket shelves e.g. an ice cream container. Or perhaps spray it with that expanding foam stuff that builders use, then mould it into an aesthetically streamlined shape before it solidifies. Spray with matching touch-up paint. Enjoy several meals out with the saved £400. Never lose the car in an airport carpark.

Plenty of shark fin antennas on eBay. Various fitments. Mostly less than £8. I would use the cover from one of those on your base. Rattle can to paint it. Fit on base with hot-melt or epoxy.

Honda Civic - Shark Fin Antennas - Something to Avoid? - TinaS

John F - I was wondering when someone would mention the old wire coat hanger trick and it had to be the master of the budget solution! Personally I stay well away from that expanding foam stuff ever since I tried to fill a hole in a ceiling with it and then had to deal with the resulting carbuncle but it's a lovely thought.

Rerepo - I did have a good look at the various shark fin aerials available for small money but the only way of guaranteeing getting one that would fit over the base on my car would be to buy a second hand Honda part for £50, dismantle it and use the cover though it's deisgned to be held in place with screws which are only accessible if the whole assembly is removed. Plastic does get brittle with age (there are bits of broken plastic from the missing cover still attached to the screws) so at least a new replacement should be stronger. Presumably the makers of such things do not make allowances for impact with a bit of flying English oak tree!

Isopon plastic padding, perhaps the fibre reinforced stuff. Or glazing putty

Don`t they do universal covers that stick over the original, friend of mine bought one from ebay for 8 pounds plus delivery and it stuck in place, took all of a minute to stick on, still on there over a year later so can`t be that bad considering all the bad weather we had
