Another matter all together.And what's the UHF side?
Larsen says that on 440-450 MHz it's a "Colinear" with 3 dBd of gain.
Another matter all together.And what's the UHF side?
If I remember right the top section was about 16" (5/8 wave) and the bottom section was about 18" (almost 3/4 wave).And what's the UHF side?
A Motorola AVA on an ATV? You must be a glutton for punishment!
The antenna starts where the coax sield and ground plane ends.I'm just looking at where I should start my measurements, when trimming the physical length of the antenna element on my and NMO magnet mount roof antenna.
Well, I guess it's difficult to determine where the shield for the cable is attached inside the magnet mount antenna. The cutting guide just gives you basic numbers "18 inches for 152-162 MHZ" they don't tell you where to start your measurement from, that is why I'm trying to determine i where and how much to cut the element element to it to get as close to an accurate SWR electrical length without having to purchase the fancy SWR meter and a ham radio to transmit with in order to achieve a close match.
