My before numbers were crap! Worst reading was SWR of 3.5 on channel 40!!
Ended up trimming about 1.5 inches.....and yet to highway test, but what a huge difference in transmission range locally from the Lil Wil!! Roughly 2.5 times further in my neighborhood with obstructions like houses & trees using a Pro-107 scanner + 7" rubber ducky. So I'm looking forward to seeing a very nice distance boost on the highway.
My after-tune-up numbers are very respectable at:
1.4 on channel 1
1.0 on channel 19 (needle motionless when keying up)
1.3 on channel 40
I understand 1.5 works out to about a 4% loss in transmission power, so I'm grinnin' at this stage. Especially considering this is my first SWR tune up. I'm stoked I went to the trouble.
I was going to pay someone to tune up the antenna, but they weren't available til tomorrow....so I decided to pick up the Radio Shack 21-534 SWR Wattmeter and give it a shot.
