AM/FM Booster to fit a Goldwing GL1800

Post by CrusaderPhil »



I am after an AM/FM antenna booster that will fit the plugs and the socket on a GL1800, i bought one off Amazon but the standard plugs fitted on it are too big for the Goldwing, the GL1800 has very thin plugs and sockets, in photos they look the same but the diameters are different, if anybody knows of adapters to go from a standard plug/socket to the slim plug socket that would help.

I wish you luck in your search but I know of no AM/FM booster that actually works even if it does fit the Motorola Jacks that are on the GL1800.

Do not know if it works on a GL1800 but I have tested it on my classic car which has a long cable from the rear to the radio and it works with that, that has standard diameter plugs, back in the 60's when I used to fit car radios most radios had a capacitor accessible through a small hole, adjusting this would match the impedance of aerial lead to the radio, modern radios do not seem to have that.

Are you specifically looking to boost AM performance, FM performance, or both?

Over the last few decades, the amount of noise-polluting electronics has degraded AM reception dramatically. Here's a Canadian government document with some background on the topic: https://www.ic.gc.ca/eic/site/smt-gst.n ... 01379.html

I've read elsewhere about a rider with a 2018+ bike that used a dedicated UHF antenna setup for his amateur (ham) radio temporarily on the AM/FM radio on his bike. Apparently, it was a significant improvement that proved that the problem is actually the antenna, and not the radio itself.

As much as you'd like to use the radio, it's readily apparent that the system is less than ideal. A receive amplifier will not substantially improve this on an '01 - '17 bike.

It is FM we mainly use in UK, the quality of the FM signal is very poor compared with that of my Car and my Van's radio Ok if you are in the City but once you get out on the open road, nothing, whereas my car radio on the same roads is fine, even the radio on my SATNAV and on my BT helmet radio are fine, I have a booster that actually improves the VAN's radio but is fitted with standard diameter plugs not the ones that fit the goldwing

What about using one of the many Android or Apple apps that allow you to receive broadcast signals from your cellphone? As long as you have a cell signal for your phone, you can receive the broadcast stream I would think...

To much messing with an app, phone not connected to sound system anyway phone just connects to helmet using BT my system is wired as follows, I have a Yatour YT-06 with a 1000 MP3's on a card connected to CD harness, Riders Intercom is connected to a Sena SM10 which sends output from sound system to 2 helmets if intercom button is pressed, my SatNav is connected in to SM10 using AUX socket by cable, If I had a Garmin SatNav the Garmin would allow phone to connect to Garmin and I would not need to hard wire to SM10, as it is my phone has to connect to BT headset together with the SM10, it all works seamlessly, SatNav mutes sound system audio, my phone auto answers calls and mutes sound system also, if I can just get a better RF signal it will be great

Something to consider - Some of the "Not-so-well" designed LED lights generate RF interference. This can swamp out weaker FM radio signals, and a signal amplifier will not help because it will be amplifying the interference, too.

If you have, for example, LED Headlights, try pulling the fuse for the headlights so they are dark and drive around the block to see if your reception has improved any.

Check the ground strap on the antenna inside the trunk. Goes from the antenna mount to a screw on the bottom of the trunk. They have been know to break.


Adding an amplifier probably will not increase signal. The amps are mainly used to push a good signal through a longer cable.

Ground strap has been removed cleaned and refitted, I suspect there is an impedance miss-match but the cable is part of the harness I have tried another aerial was not a Goldwing one but was similar and made no difference.

It probably *is* the ground, but might not be the ground you're thinking of...it may be the 'G2' ground you need to work on.

Now, about those DIN 41585 ("Motorola") looking connectors that Panasonic/Honda used, it's the only place I've ever seen the smaller version of them.

I can't find 'em.

I was loosing my radio signal last year and had corrosion at the antenna connectors. The one under the seat. Cleaned them with a scotch bright pad or light sandpaper and all is well.

If it is corrosion on the connectors, pick up a can of Deoxit D5. It will clean the connections and protect them from further corrosion.
Pricy, but works.
