VHF antenna types

[FreeSoup]

Meant to include in the original message. Have heard good thing about Metz. I have had good experience with GAM Antennas. Also, if you have AIS and a splitter, you should think about getting an antenna tuned for both AIS and VHF. Cheers!

Seems like maybe the right forum? Will do more digging on the boat, but any idea what the antenna behind the light and radar is for? About 2' tall.

Cheers!

That looks very similar to a Wi-Fi extender aerial that I have.

Funny, had a similar thought, but not aware of the actual booster/extender anywhere. Time to do some wire chasing! Thanks for the input!

There are much better cables than RG58 available now for similar prices.

Some old Radar antennas required a specific length of cable, but that was for timing purposes, not tuning.

Thanks - please tell me: 50ohm impedanz which type / name / specs / vendor ???

M&P Hyperflex 5, Ultraflex 7 etc.

Virtually all the good quality antennas produced for the the marine market will have the antenna cable heat moulded into the base of the aerial to avoid any water ever getting to the feeder/coil connection in the base .
Normally a encapsulated soldered joint. The coil printed on a PCB and soldered to the feeder, meddle with this at your peril.
Any extra connections added to enable the use of some fancy cable will lose you far more signal than the virtually immeasurable gains likely to be achieved over the sort of lengths likely on any motoboat.

Agreed (as an ex radio engineer/licensed amateur). I like this stuff - EXTRAFLEX BURY 7 /.300

Is this ok (below) for use with a marine VHF ? It does not seem to have the same 'protection' as the MESSI & PAOLONI EXTRAFLEX BURY 7.3MM/287", but then the ultraflex does seem better than the normal coax

I've got to renew standing rigging, so whilst the mast is down I'm going to renew the VHF aerial and coax wire, etc

ULTRAFLEX 7 - Messi & Paoloni Coax Cable

This will be fine as well, much better than standard coax. For the most part, the coax is protected inside your mast and behind panels in the saloon.
