Another NOOB

[222FL]

The sirio antennas all come with the exact numbers. They are always in MM, and not inches as the antennas are made in Italy. Where you looking at the tornado maybe? Had one of those up for about 1.5yrs and did very well. Just follow the tuning guide in the manual and you will be just fine. If you get serious about this hobby and 11m and end up finding some locals and such, the 2016, 827 or the vector 4000 are great antennas as well but will need a good mast pipe setup or tower to be used. I am currently using the vector 4000, and man it rocks!! It tuned flat and is the best antenna I've ever used as far as verticals are concerned. They are very quiet on the RX side and man they will put a signal out too! Mike is set to 26ft to the base. I posted a thread about it. It isn't an easy antenna to put together though. The tornado or the GPE 27 are good ones. Here is a photo of one that my local friend has up, notice how small the mast pipe is. It's fence rail top post.
This is the one I posted the photo of from DNJ Radio. Great place to buy from. Anyway. Have a good one. Off to work.
