If you change the base, won't that remove the GPS capability? I can not see any way that they use the antenna itself for GPS, but have that part in the base.

Try searching for a Quick Release fitting, there may also be some BNC adaptors. 3/16BSF is 32TPI, that may help.


Yes, it is "multi-band", just as an antenna on a regular VHF-hand radio is. Most of them are VHF and UHF. It's just it's length that decides which frequencies it works with.

That looks like an FM only antenna, its for the old Ignis.


Yes, now I have looked into it, it is for the old Ignis. Thanks.

Vaseline is petroleum based and would preobably do, but I used that red battery terminal grease, simply because it's deemed to be an electrically conductive grease that keeps metals free from rust and corrosion, but any decent dielectric grease should suffice. Example here


IF IT AINT BROKE, KEEP FIXING IT UNTIL IT IS

No, please don't do that. This compound has a lot of nick names. uk.farnell.com/dowsil-formerly-dow-corni...-tube-100g/dp/537019 is a good option. Works pretty much like grease. It's hydrophobic, so water doesn't get into it. It also is dielectric, so no shorts. A little bead of that stuff will keep the elements away from the connection.

Ok, thanks for the advise. I'll pop down to local car shop later and see what they have in.

I will second TaterTot's recommendation on the Dow Corning silicone grease - its first class but probably expensive; its very widely used in aviation, but I would guess any silicone grease is good with electricals AND is less prone to destroying plastics and rubber as Vaseline or petroleum based products will.

No - don't use copper grease.

The whip is 12" over all and 6" too long to pass under the door. tried to get some silicone grease today but failed, will have a look online.
