needs to be replaced with a single run of 108" (1/4 wavelength) high quality, well shielded 50 ohm coax.
If you want the capability of removing the tour pack, order an 8 foot coax with male TNC & mini UHF female connectors, along with a 2 foot coax with mini UHF male on one end, no connector on the other end
Hammz, you lost me with these to quotes, either that or my math is bad. I thought you were trying for 108" of cable but then you mentioned 8' & 2' which will be 120". Not picking on your math, just trying to understand what's best.
Thanks for the web site.

That is inaccurate.
The "Shorty" antennas are not long enough to resonate at 27 MHz, hell about the only antennas that are, are the 108" whips.
Most of the antennas have a loading coil (usually at the bottom) the coil "fools" the radio and signal into seeing a longer antenna, so the majority of the signal travels down and leaves the antenna instead of flowing back towards the transmitter, too much signal flowing back is high VSWR.
Also, The lower the RF frequency, the longer antenna required.
Channel 1 is lower frequency then the other 39 channels, requiring a longer antenna.
A properly designed load would allow a paperclip to look like a good match. Not much signal would be radiated effectively, but the radio sees a good match.
The proper tune you speak of allows for using the shorty antenna not the other way around.
Ride Safe Everyone,

Most guys don't know anything about SWR or tuning an antenna. With that said, the shorty is a better match out of the box (bag) than the OEM whip. My reception and quality of transmission improved after switching out, no doubt a result of a better match, regardless of length.

I heard back from Clay's this morning. They did not know the stock output, but they will boost them. I was told they cannot perform the work at this time but should be able to next year. They are building a dedicated building for working on motorcycle CBs.

THIS, is excellent news! If they create a replacement coax cable, all the better. I'd do both from them.

The shorty antenna IS a coil if you look at it. SWR on the shorty is lower on the lower channels at 1.8/1. The BEST I could get with the OEM long whip is 2.7/1. Borrow a shorty and an SWR meter and check yourself.
