CB Antenna projects?

[Buick Mackane]

Do it like on attached image.
Coil is 5 turns of coax on 10cm diameter.

What is that ?

[ch25]

Half wave vertical dipole which actually works.

Looks like a EFHW to me, How is the impedance matched ? Is it a bazooka ?

[ch25]

It's around 70 Ohm, no matching needed.
Not EFHW since it's a dipole.

Sorry, since I can read, no time to waste for yt mumbling, but according to displayed start picture from the movie that guy is wrong.

Its for the OP lemmy

Got it

I found a T2LT to be down on performance over an end fed when I was messing around with them. Probably by about half an S point

Great for temporary locations and portable DX though.

Rain and high winds stopped play yesterday but the Gallows Pole functions horizontally on a flat roof temporarily for now.

SWR hovers around 2.2:1 and I did hear distant voices today. There was a conversation going on at ch 19 but my attempts to get in on the side went unnoticed.

Erks!

No wonder. Polarization mismatch is circa 26dB attenuation. 4 s units. Put it vertical.
Also roof, even dielectric, but wet is worsening antenna performance a lot.

Strange how you can't achieve a decent SWR, Dipoles are pretty easy to tune, Still reckon it's too short.

Thats a word I haven't heard for a long time, I've never owned one.

Yep, I totally understand that, its just the rain and high winds that prevent me from trying it vertical.

It'll only be a temporary try vertically as the whole structure wobbles like jelly in anything over a light breeze being made of roof battening! Deffo a bit of make do and mend going on here.

I'll try longer 'elements' again and start trimming again to try and get the SWR down if I can get it vertical soon. Still 'orrible weather here. I wonder if its my SWR meter too possibly out of calibration?

I had another trawl through my old cupboard at Mum's again today, I've found another 2 SWR meters (how many does one guy need?!) and some other goodies I'd totally forgotten about too.

I'll update over on the other thread ( viewtopic.php?t=60604 ) and keep this one going just for antenna fun.

Connect your SWR meters the other way round to test them
