VHF??? Thru our stock am/fm or 2nd CB whip?

Guys - got another one here. Has anyone tried running VHF comms thru their stock CB antenna's or the VHF side?


For two trips coming up, we'll be circumnavigation looping road routes around various islands; all the while keeping tabs and keeping in contact with the yacht races 2 or 3 miles offshore an reporting back.



Therefore, a small 4-25w marine VHF radio deck will be mounted up forward.


Question is: whats the best antenna options for us 1500's without looking awful?
I'm happy to go without am/fm for the trip? But can we broadcast VHF through the am/fm whip or a second CB whip?


Cheers,

Neither antenna will be tuned correctly. The CB antenna is HF not VHF band and the FM antenna though VHF is optimized for ~98MHz and won't have proper loading for a transmitter. You risk frying the transmitter, especially at 25 watt output with either antenna.

I can't quite tell from your avatar photo, but if you have a luggage rack you might want to jerry-rig a proper VHF marine antenna onto it. Might look a little funky, but would save your transmitter. Also lining the underside of the trunk lid with aluminum foil and grounding it will help provide a "Ground Plane", although generally marine transmitter antennas do not require one.

In short, I'd be looking for ways to mount a proper marine antenna on the bike.

as said, do NOT use any existing antenna. Laws of Physics rule all of them out.


Every radio frequency requires its' own specific antenna tuned to that exact frequency ( narrow band of frequencies ). Anything else will fry the transmitter of that radio.
The receivers are a bit more forgiving, they just won't receive as well as they should.


you will need something like the Marine antennas that do NOT require a ground plane, most of them look like Airplane wings, or you can get the vertical monopoles that are really a dipole that is center fed internally. the GW does not have anything metal mass that can even be considered a "ground plane", the tiny bit of foil you might line the trunk with will actually be quite useless.


you don't specify what frequency 'VHF' radio you are talking about.
VHF is a very loose term covering from 108 mHz to 220 mHz


what is the brand, model # of the radio you are using?
Actually, most of the VHF radios will actually do a good job with just the Rubber Whip antenna supplied with most of them. ( hand helds )

Hi guys - thanks!


The marine VHF freqs are 156.050MHz up to 162.025 MHz (although rarely).
Yes, I do have a luggage rack on the trunk but no lower rails anymore on the saddlebags.


I do have a steel hitch of course, but I agree that is such little grounding material to work with. Perhaps, a long wire wrap or coil would do, but I doubt it.


The marine antennas (independent grounds) - I have no problem throwing that on, but I just feel like three whips will look ridiculous - what do we think about taking a standard marine stainless steel 3 foot whip, and clamping it to the bottom have of our am/fm whip?


or is it possible to perhaps, take a standard independent ground Shakespeare marine 3' antenna, and somehow work the coil and whip into our GL1500 mounts...anything like that been done? Anyone have any ideas on how to make it less custom looking and more stock looking?


Cheers!

personally, I don't give a damn about what other people think of my antennas.

back many years ago, I put a military tank whip on my 1951 Plymouth so that I could tap out the CW ( morse code ) while driving back and forth to school in Norman, OK from our home way out west of OKC near Yukon.
that antenna was 16 feet long, I held it up vertical with Trot Line cord while traveling down the highways......

pulled it down next to the roof when it needed to go underneath something low.

I advise you to put on what works, and yes, if it is a 3rd antenna, so what?
it is needed for the radio you have in use "right now".


there is a nice new Volvo running around our home town here, that has 5 antennas on it..... screw the world, he has want he needs.

That's where I'd feneggle a mount for the antenna. Being a marine antenna probably not necessary but I'd run a ground wire to the luggage rack and antenna.
+2 on what John said about looks, it IS the antenna you are currently using..

at about 55 mph, the antenna would lean back about 45
it was a military tank whip, with those screw together sections about 3 feet long each. the mount itself was beefy like all military stuff, huge heavy spring.... the whip had a lot of give, and that spring would let it lean back.


but, at slower speeds, I would reel in the Trot Line and pull it down to cab level and hook it under a hook i had clipped to the door jamb.


I suppose it got a few "WTH" looks, but I don't care. it was very efficient and I held regular conversations with friends down in Columbia, SA every weekday morning.
