99 GL1500 FM Antenna Screw?

[zeoran]

I have a 99 Gl1500 Aspencade. The left-side antenna (which I believe is for FM) suddenly almost fell off when I came home the other day. I noticed that there's a small, long thin screw that's supposed to go in there with an alan wrench head to it. Obviously, the original screw itself is long gone. Where in the world would I pick up a new one? I currently have the antenna secured with a zip tie but I'd like to get it back to the original securing method.

That left antenna is for the CB radio and the load (coil) in the center is where I expect you are talking about the screw. You can check with Lowes or Home Depot or any of your local auto parts dealers and probably find one. If not try a specialty company (screws and bolts) to find what you need.

Do you know what this type of screw would be called? Just walking in and saying I need a screw for my Goldwing antenna isn't likely to get me far. Lol.

A picture would help. I take it this isn't a part that Honda sells by itself? Where the whip attaches to the loading coil there is a set screw for adjusting the whip length but I don't see how you could zip tie that. There is also a larger set screw with a special nut that holds the lower section to the hinging part so I'm not sure what you are talking about.

Maybe what you are looking for is in this picture of the parts?

It's where the antenna plugs into the socket itself. Pictures attached.

It's called a set screw, and any small allen screw of the correct size/thread pitch will work. I don't know if it is available separately as a part (doubtful).

[zeoran]

Unfortunately, I don't have any screws of that size. And when I looked through Home Depot, I couldn't find anything of that type there either (neither could the nice store worker who helped me)

Maybe I can get a specific part name for it that will help. I'll be happy to spend like $10 to get a replacement screw, but I'd rather keep the zip-tie before I buy a whole new antenna just to get the small screw.

I just Google searched "gl1500 CB antenna set screw" and it came up with a few options, but all listed the part as out of stock. Maybe I'll take it by the local shop/Honda Dealership on the off-chance they have something.

Any good industrial hardware store will have what you need. Box stores probably not.
One of my favorites in your location.

Thanks for the referral.

Any idea specifically what size I need or should I just take the antenna into the store & ask them to fit it?

Just take in the part and tell them it's Japanese.
Unfortunately, there are two flavors of metric. DIN (Deutsches Institut für Normung) and JIS (Japanese Industrial Standard) The diameters are the same, but the thread pitch is different. Actually, since that bike was made in the US who knows it might be SAE if they bought it from a US supplier. No matter, they will be able to fix you up.

From what I see of where you have the nylon tie wrap, I do not believe that is a threaded hole. On the antennas I have, that appears to be nothing more than a hole bored for a pin. The pin is supposed to hold the antenna parts together. I have never disassembled that part of the antenna but it would appear that the pin is a press fit. If it were me, I would probably try to locate solid 3 mm pin to press into the bore. You could also try using a 3 mm threaded machine screw and secure it with a nut and some blue thread locking compound.

Looking at my '99 and I agree that it's not a bolt or a set screw. It appears to be a pressed pin. A roll pin from the local hardware store would work, too - trim to the right length. It's a bit of a hack, but a little nicer than the wire tie.

It depends - on one side of the load coil it looks like a roll pin, on the other side is a set screw to allow you to adjust the shaft length to adjust SWR.

I took another look at the antenna on my '99. Looking specifically at the left-hand antenna (facing forward). The lower part of the antenna (sorry, don't know the technical jargon) has the pin. Further up the antenna, there is a gizmo that has set screws. However, from the OP's pictures, I think it's the lower portion that's in question.

Pics of both below.

Based on your picture (can't see both sides) it does just look like a metal pin. it's smooth on the side shown in your pic. But that's exactly where mine is missing. (no idea how it came out/off)
If there's no threads in there, a screw won't work. But I'm not sure how a pin stays in either. I'm curious what the other side of yours looks like. Is it also smooth?

I will assume that you have an antenna on both sides of the trunk. The right side antenna should be the AM/FM antenna. Both antennas, are constructed similarly. The difference being there is no antenna loading coil on the AM/FM antenna. That being said, if you look at the AM/FM antenna, you will see a pin in the same location as the CB antenna where you have your nylon tie strap positioned. Those pins hold the fold over portion of the antenna to the base of the antenna body.

A machine screw will work for you. It is, I believe, a 3 millimeter hole. A 3 millimeter machine screw that is at least 20 millimeters in length will work to hold the antenna together. Simply slip the screw into the hole and put a nut on it to hold it in place.

A roll pin would work as well if you can find one to fit that 3 millimeter hole. However, if you are not a mechanically adept person, a machine screw would be probably be easier to install.

[zeoran]

I do have an FM antenna on the other side. But the antenna on the right side has a flag mount on it, so it's not the same as the other side.

I'll head to the hardware store referred earlier & see what they can do for me. Failing that, I'll head to OC Motorsports & beg them for a solution. The zip tie will hold it for now, it's just not aesthetically pleasing.

[MaineStreet]

Best I can tell the pin is smooth on both sides.

I agree that nut/bolt combo with a dab of loctite would suffice (or a nylock nut)
