I am interested in a dual band, circular polarized antenna system, I like the Gulf Alpha system, from the reviews i have read. But their web site is a bit thin on info. I go to the dual band section, it talks about FM antennas...not sure why they would be FM... they arent tuned for SSB part of band or what?
What is the model number of their satellite packages?
Anyone use them? I saw an Eham review of one system, great review, but no antenna model number.
Please direct me...

Or from Peter's main page select Online Catalog / Satellite Antennas
Don't select Dual Band area.
Model No. 70CM-8ELSat and Model No. 2M-5ELSat

Bob,
I am not aware of a dual band circular antenna made by anyone. I do own a dual band antenna Gulf Alpha used to make, but it works as a linear antenna on each band like the 'Arrow' antenna.
The Gulf Alpha antenna is a beautiful piece of craftsmanship. It is the most ruggedly constructed UHF/VHF antenna I have ever seen. Truly an antenna built to withstand whatever is thrown at it! When in doubt they machine their parts from solid chunks of aluminum!
Performance seems to follow exactly what one would expect. I believe they get as much gain as can be expected from the boom length used, just as any other modern Yagi. Modern antenna modeling has put everyone in the same ball park for the same boom length.
When I was shopping for station antennas I wish they would have made the longer Yagis they make now as I would have bought them.
73, Joe kk0sd

Hello Bob, Joe et al
I must agree with Joe. I have two of the Dual Gulfalpha antennas for working the LEOs. Nicely made and easy to assemble. I've had mine for about 2 years.

Either of you guys ever had the chance to compare to say, something like the Directive Systems yagis? Better, worse? Worth the difference in price?

Sad to say, it may be an idle question. The dual-band antennas are no longer active items in the catalog. Looks like they're concentrating exclusively on higher-gain single-band yagis, as far as the amateur market is concerned.

Duffy.
Your e-mail system is broken. It doesn't accept incoming mail so I've had to reply via the reflector.
Hi Duffey
Most of what you say has basically been observed here. Britain makes very little these days. The far east does it far more cheaply and has pushed our manufacturing businesses out of the market. Those tat do survive tend towards the expensive niche markets. We've got your 222MHz problem on 70MHz. We've got 500KHz of band that we share with the military. There is very little, if any, commercial gear available for that band although several European countries have recently been given access so the market may open up.
I do actually have reason to be concerned with the future of the American 220MHz allocation. Come this summer, I will be emigrating from the UK to the US to spend my retirement in your country. I have a wife from Dayton OH who wants to go home. I've held a US license since 1999 and am a VE, conducting exams in the UK. I guess the US will be something of an adventure.
