Avanti AV101 Astroplane / New Sirio Top One


Just wondering if anybody has used one or has any experiences with the performance of this antenna.

A similar model used to be known as the Avanti AV-101 but Sirio has brought this modified version described as a 1/4 wave out again and named it the "Top One", (I am pretty sure the original design was a 5/8 wave?). I cannot find much UK info were this type of antenna can be bought.

Yep used one in the 80's, it worked superbly although quite a narrow bandwidth if I remember correctly.

New Sirio Top One UK Info


I have been in touch with Truck-King regarding these antennas and they are not prepared to stock them as the Euro rate does not make it worth while importing them at the moment anyway.

Thunderpole Communications said they can supply an equivalent antenna by KP-O for £69.99 though I'm not sure about the quality of those.
There is a few flimsy looking copy's of this antenna about by CTE and other brands.

Anyway I would like to try one out as they are supposed to work very well at lower heights and if surrounded by hills or mountains as I am, so I got in touch with Sirio themselves in Italy who gave me the details of there distributors in the UK (Sharman MultiCOM LTD) Sharman say that this antenna should be available in the UK by Mid October for around £99. Knights will also be selling theses in mid October too for the same kind of price.

I'm still interested to here of any reviews or experiences with the original Avanti AV101 astroplane (or Tagra BT101?) from the 70s/80s, if anyone would care to write a short review it would be appreciated.

Hi FB220, I know! they are a bit weird looking, I remember looking at them in magazines in the 80s and thinking what the heck is that! The more I read about them the more I want one now! emoticon
