No problem. I used to use a station master for 20 and 10m before I got the tribander. Worked fine enough with 4 radials for each band. I bypassed the loading coil and then used the radials to tune the antenna into band.
Hi Rob
I made a similar antenna for 20,40 and 80 with a biger coil 65 turns a aligator clip to change bands the radiator with 18 feet no radials cause was instaled on my camping trailer,worked very well the only inconvenience was that i had to climb to the trailer roof to change bands.
I see pics of staion master for 11 i want to build one but don’t know what size is the coil in diameter,looks like 1 inch and 10 turns
Thankyou Rob 73 de ve3tww/va3lmx
10 turns is right, but its closer to 6cm, i do not have one here to measure. Not sure what that is in inches. If you look at this image, the shielding conduite is 25mm so 1 inch, so the coil is at least 2 times that.
Hello Rob
Is the cb station master use ground wires or radial
Thankyou and 73
Depends on if its ground mounted, or mounted in the air. But, assuming in the air, 4 elevated radials at a 45deg angle is perfect.
Thankyou Rob
