Picture courtesy of Ian Hughes from WalsallThe Avanti Sigma 4 was probably the best omni-directional base station antenna ever built.
The design was simble, robust, and extremely effective. The performance was legendary, and anyone fortunate enough to own one would probably have worked all around the world back in the '80's.
There were several copies such as the Tagra BT-104, Comet 444, Saliut 27, and the Sirio Vector 4000, but these later variants were not as capable of wind survival as the original Avanti Sigma 4.
A picture of the original Avanti Sigma IV can be viewed here.
If anyone has any more original pictures of this true classic antenna, perhaps they would be kind enough to share them with us here.
If you have any pictures or information, please email us with your experiences.

I`ve got one of these going rotten at the back of my shed, Its the last bit of CB stuff I`ve got & it hasn`t be used in over twenty years.
I once spoke to someone in Papua New Guinea whilst using it, from Lancashire that`s quite a way
I think I`ll see if its do upable

this was the best antenna i ever owned. had it mounted on a long mast and got very nice qso from all over the world. if i ever want to have a base antenna again i defended start looking of one again.
I had one in perfect condition, it had been made up from original bits and pieces i had bought over the years, it was in storage in my dads shed but went missing, he either chucked it or it was stolen? Gutted as these are rarer than rocking horses, all thats left is a spare ring, i don't expect i'll ever find one again, i had searched for years to find that one, before that i had a fake and before that a silver rod. All were 45ft up on scaffold poles.
