Default sirio sy 27-4 4 element beam rotor information


Hello I need some advice on a rotor to buy to turn the sirio 4 element beam the rotor i'm looking at to purchase is a hygain ar35 light weight tv antenna rotor.I was wondering if this rotor would do the trick for what I need or should I just buy a hygain ar40 because i'm on a budget I don't want to waste money on this rotor if it won't work.I think this antenna only weighs about 13 pounds.I would mount a 3 foot mast to the top of my tower and then mount a 5 foot mast on top of the rotor and then mount the antenna on top of that.Another question I have is it says on the sirio website this antenna has horizontal polarization I was wanting to mount it vertical so I can direct my signal vertical instead of horizontal any ideals?This will be the second beam I ever ran I had and ran a maco 103c on a 35ft tower before and I just wasn't happy with it's performance so that why i'm going to put up a 4 element beam this time and see how it performs for me.I want to be able to talk to my friends about 65 miles from me.I will be running a older black face rci 2950 with a superstar dm452 echo power mike and a cobra xl250 2 pill amp behind the radio.Hopefully some body can tell me if the hygain ar35 will hold up turning this antenna because i'm going to concrete the tower in the ground about 4ft.I don't want to have to take the tower down later to change rotors I don't climb towers i'm scared of heights lol.

I'm no expert but research shows that rotator is rated for 6 meter beams and loops and I believe your antenna is for the 11 meter band and will have considerably more wind load so the ar-40 or the cd-45II would be a much more reliable choice.

Thanks for the info mackmobile43 i'm thinking about buying a yaesu g450a with control box from ham radio outlet for $250 or a rebuilt cd44 with control box from norms rotor service for $299.00.I talked to a guy today from ham radio outlet and he said he has a yaesu g450a turning a beam for 13years or more and never had any trouble out of it.I been doing some researching and I think the yaesu or cd44 would be a better rotor than the hygain ar40.The yaesu g450a has a 10 square feet wind load and the cd44 has a 7.5 sqaure feet wind load and the hygain ar40 has a 3 square feet wind load.

Yeah I would rather do things right the first time.I just hope after I spend all this money that the antenna works pretty good.I had a maco 103c before and I thought it was junk.

555 why wouldn't you see a difference in going from a 3 element to a 4 element beam.The 4 element has 1 more element and a longer boom so wouldn't that mean the 4 element would have more gain.

Yes I too would like to hear his reasoning for that comment.
