I have had my Sirio Top One up in about a year now and I am very pleased with the antenna.It is not as broad band, but 27 and 28 MHz working very well.One off the benefits of the antenna is that it is lightweight and is only 3.6 meters tall and works well against both verticala and horizontal stations,very stabil against strong winds. What I think it's a price worthy of the antenna and that is easy to handle and install. 73s Ulf

I have heard they are of similar performance. I have talked from Australia to EU, and from Alaska to South Africa with mine Astroplane. A wonderful antenna and the smaller size makes it ideal for limited space installations. The higher you go with it the bigger it behaves, too!

His is 36ft to the tip (which it radiates from) and it performs excellent in rx and tx, when i go round and use his set or we run comparison copy's it keeps up with my imax all day, which is surprising to me but it does. I am well impressed and if it wasn't for me needing a straight up pole type antenna for tree mounting i would have one up tomorrow. The bandwidth is 2 megs and i have dx'd west coast usa and many more from this very underrated antenna. They are quite well made too the only tip i would give is to tie wrap the lower ring on the groundplane to the pole allowing for a little play but not allowing it to sway too much. Knights have the sirio topone in and an astroplane exact copy in too i can't vouch for that one though. An impressive antenna to me, i don't know how it works but it does.

Cheers Mark 554.

The original Astoplanes are 5/8 wave, the Sirio is a 1/4 wave. Look closley at the feed point on both antennas, that will give you a clue. I have a 5/8 clone up and is superb. I will post photos and points of interest under the heading of Astroplane later for those who are interested. If you do a search on youtube under Astroplane or rradishuk there is a video, cna't quite get the link to work. http://www.youtube.com/user/rradishuk

It seems like it is something to do with my coax. Anyway I now have new RG213 (30 meters) fixed on to a new Sirio Top-One. My mast is around 16 feet above ground level and I would say the tip of the antenna is around 28 feet or so. The problem I am having though is that my SWR is a little high. If I have 5W FWD power my SWR reads around 2. If I increase my FWD power my SWR goes up. Great, just when I thought I might be back in business I still have problems. I have not yet made a RF choke (Balun) would this increase my SWR? Is the Antenna not high enough? As I write this I hear someone on T5 from 110 Div so I am getting ok RX. I think the cone bottom tubes is slightly too short, around 1300mm. They should be 1305mm. My Gamma match assembly is spot on at 580mm. My old Gain Master is laying in my garden. I think that water could have got from the antenna and into my coax, but that is just a guess. I did have some water droplets inside the antenna when I took it down. Any Ideas guys please?

I have only taken my Sirio Top-One down, Put together my Sirio Gain-Master, Put that up and now my SWR is sweet; 1.2 full PWR on FM Muppets. I seem to have more static noise but I do think I am hearing a bit more. These antenna's have been up and down more times than a yoyo (clean version lol). Oh well I have my can o beer and I can sit in front of my set again. Lets see how things go. Cheers and Beers Sheridan.

I had to alter this measurment by 30 to 40mm but i can't remember which way for a near flat swr on 555. Best of luck

As The Crowman says the new Sirio top one is at first glance similar to the astroplane but the astroplane is electrically a 5/8 wave in length compared to the center fed Sirio top one which is a 1/4 wave length, two different antennas. From what I hear the Sirio top one is quite a good performer too. As mentioned too knights are doing an identical copy of the original astroplane (the BT101) in limited supply for 74 pounds. I would love to here comparisons between the old avanti astroplane/new BT101 compared to the Sirio top one.

Mine is on a 27' mast, putting it at almost 36 ' . If it will make a big difference, I will change it, if not I'll just leave it. It works really well the way it is Edited by Tuner, 30 Mar 2013 - 00:18.
