A load of waffle, is that a technical term from planet Conor for I'm out my fucking depth here? Someone throw me a lifejacket?
Because something is stock don't mean its right.
You never mentioned cutting anything, especially bullshit, you stated a 108" whip is a 1/4 wave at 11m, i proved you wrong again, as CK has just stated 102" is stock length in the North American continent, do you propose they cut theirs too?
Think I've already proved that would worsen things,not improve them. Incidentally 108 inch whips originated from the States, back in the early 80's when cb boomed in our country, (you probably missed that) the retailers bought huge amounts of surplus ones as the cb boom in the US had already died, back then only whips that were 102" from what I recall were fibreglass/plastic coated which would change the dielectric constant and signal propagation speed compared to air dielectric and shorten the whip just like dielectric in coax does.exactly the reason air celled coax has a much higher velocity factor than solid dielectrics or foam which is a cross between the two and due to its lesser air content lies between the two in velocity factor too.
Where the crossover to 102" stainless steel ones came from i can only imagine one dumbass manufacturer got it wrong and others followed and in the common case of most manufacturers won't change it now as that would damage their ego's,
cb'ers in the USA and Canada have been posting for years 102" whips are too short and they have to use springs,which have a copper braid running inside to tune them,as it becomes part of the radiating system.a bit of solid stainless steel rod tapped to 3/8 th thread at both ends would serve the same purpose,if i recall you can get hexagonal spacers of that size although not sure if they'd be long enough.
MFJ are one company that either realised their error or didn't buy that shit in the first place,I think you'll find their MFJ-1966 is stock 108".
