DIY: UHF CB 9db gain collinear antenna
Posted: Wed Feb 08, 2017 3:31 pm
I'll let this first lot of pictures do the talking.
Long story short, my current base station antenna for my UHF CB at home, is crap.
Like really really bad.
I needed something that would do it better, hence I got researching, designing, planning, sourcing, making.
Before housing, connecting, elevated ground system and pigtail, it comes to 170cm ish.
Pretty happy with it so far, though i'm sure some of you experts will point out some obvious flaw.
Radiators (tubes) and conductors (wire) cut to size:
Custom made spacers:
Stripped back to the right length:
All shined up, ready for soldering:
Again, all shiny:
Soldering (don't pick on it ), which was very hard with the copper pipe:
Heatshrink, then tape, then heatshrink, then tape (overkill much):
170cm before housing, elevated ground etc.:
All done (well, the radiators and conductors):
It's still a work in progress, but progress has ground to a halt.
Unfortunately, life has got in the road.
