sigma 4 - vector 4000 home-brew CB antenna

here's my home made cb antenna . if you're interested there's a thread about making it at .....
www.worldwidedx...
the first several pages are about me finding out my initial ideas weren't as strong as i wanted them to be , but eventually it came along and i'm mostly satisfied with the results . i only have a few trivial cosmetic changes i'll make when i'm really bored .
thanks for looking :)

Wonder how much it weighs? Beautiful build💙 I really like how the base of the antenna attaches over the mast pole instead of being clamped I'm going to go this route as have had clamps rust & break & distort the bottom section on these in the past owned 3 of them👍👍

Hey= I commented on the forum awhile back about it. Tell me again why did you put the coil on it. 21

Congratulations to your homebrew antenna. I`ve a clone from TAGRA, the BT-104. Best 73's to you.

[@atticman2011]

L@@ks Great, would love to hear how it performed,and what was gained with the coax choke.

Also the j Pole antenna works good on CB Google the j Pole calculator it give you one for 10 meters CB is a foot longer I made one long side mite be 27 or 28 foot the short side was 9 foot long

Are there any further details on its performance. Am interested hearing about it, such as SWR, distance of signal and whatever you found out.

Can't find link to antenna info

This was modeled using EZNEC (or 4NEC2) and it showed what kind of pattern and had what amount of gain?

Cool antenna ! How does it perform ? I have a restored CTE/Saliut LW 150 and it talks and hears real good. Thanks for uploading ! FOUR NINE ZERO CURLYJO RADIO 73's

looks like a cool antenna

[@robertcline9174]

I have the Avanti sigma 4 original but, needs Gama match upgrade to connector, it is not good so239 loose, but mine is modified with groundplane, and spider webbed outside, and inside x2 later ,it will be 3 wires inside, what a gain difference on rx and tx 3 dB with groundplane ,

[@JeffB1961]

i used a heavy duty mobile roof mount connector for the coax feed to the hot on the gamma match feed .

[@mt02oct]

hi mate can you please send me the parts list on how to make the antenna and what type of socket i need for the coax to plug into so i can bolt the gammer rod to or is there a link you can send me please .. i want to make 1 from scratch aswell .. many thanks

[@JeffB1961]

thanks for the interest . i'll be installing this antenna at a new location after new years and will make a updated video about some changes i've made and i'll be using a pixel 2 phone so the video quality will be much better .
