300 divided by 27.185 equals 11.03 meters. Last I checked there were 434.25197 inches in 11.03 meters. Divide by 4 equals your quarter wave copper wire..
108.5629925 inches for 27.185 mhz.
Not sure how that 102 number came up but not accurate

Precisely why the shorter antenna needs to be tuned above a piece of wire that is mathematically accurate. Afterwards the physical length is irrelevant as long as it is resonant.
Then you can mount it underneath and have the peace of mind of knowing the upper antenna is the only one requiring adjustment.
Otherwise you will drive yourself crazy. -
MY FRIEND......Im drove past crazy now..I had to come away from it before a sledge hammer went to it all..All i got for wire is not copper,just cheap electrical stuff..rabbiporkchop Thanks this. -
If you measure a stainless steel whip antenna including the length of the spring and the ball itself you should be really close to 108 inches. They come in handy for testing other antennas even if we don't use it for an actual antenna.
Changing the ground potential beneath an antenna appears to change the resonant point of the upright antenna you are trying to tune. If the ground element is slightly off it will drive you nuts trying to figure out the issue.
Helps to understand the math. -
but your still getting them to try out and see if your receive improves ??? need to get that Anderson quick dis-connect put on your power cord to the radio so you can run that 8 ga.down to the battery !!!!!!
-
yeah i do..I keep forgettin about it..#### antenna stuff has me upset that i cant figure it out..Im still gettin the 7ft ss..
rabbiporkchop Thanks this. -
the best receive i ever achieved was in 1994 off of 2 Wilson 2000 antennas that were actually set up correctly.. 30/35 miles was achievable quite often...on a freightliner truck......... but back then they were more metal and steel not this plastic/fiberglass crap that goes on today....quit driving yourself bat #### over this. the best advice you've been given came from ridgeline keep it simple and don't over think it....
-
both you and rabbi are on to something with that duel setup deal for the back of trucks.... if you guys could get it to the right ding dongs of the world !!!!!!

Once he sees how simple it is to configure a single dipole on the driver side I think he will be more receptive to the other idea of stacking two of them on the rear for additional gain
bored silly Thanks this. -
I'm not getting where certain people are getting this gps/quall-com ignition noise from I get none of the above....maybe I'm just lucky I dunno
