[amsat-bb] Re: Arrow yagis
Hi George, Arrows are great antennas -- when I first put up my az/el system in the backyard I used an Arrow 4-element 2-meter yagi for the uplink, and it worked just fine. One thing I noticed was that after a month in the elements / rain, the studs connecting the aluminum elements together had corroded pretty severely -- I think the aluminum didn't like all the rain, and I could barely get the elements apart. I've seen some reports of other hams using arrows fixed on rotors in dry environments (Arizona), but if you're going to leave them outside in the rain, you might need to take precautions to prevent corrosion of the element connectors. 73 de Dave KB5WIA http://kb5wia.blogspot.com On Fri, Jul 22, 2011 at 10:12 AM, George Henry ka3...@att.net wrote: Anybody have any experience with the solid-element single-band yagis from Arrow?

[amsat-bb] Re: Arrow yagis
My satellite truck is currently using the 4el VHF Yagi from Arrow Antennas. They are very well built and can be ordered with a Type N connector for a small extra charge (well worth it). The 7x7 Arrow II is what I use for UHF on the truck with a coax relay to switch between horizontal and vertical polarization. I am using a Mirage UHF preamp powered through the coax for that setup and it does work well. The 7x7 UHF Arrow went 5000 miles at speeds over 70mph at times and the elements never shook loose. Dollar for dollar, it is hard to beat an Arrow antenna. With over 2000 contacts in 32 different grids over a 5 week period, it's hard to say they don't work well. Arrow Antennas is now under new ownership. Tim Chapman, KB7MDF, bought the company and is in full production. Tim is really excited about the business and has the drive it takes to ramp up production and introduce new products. Suggestions have been made and he is looking at them. I loaned my Arrow II (v/u) to a friend and when it was returned, one of the inserts that allows the threaded rod to screw into the arrow shaft was missing. Tim shipped a replacement element, a few inserts and some threaded rod, no charge. It is a mystery as to how that insert was pulled out. Once the new one was hammered in, it was in there solid. Customer service is great. 73, John K8YSE ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member? Join now to support the amateur satellite program!

George, I had the same experience- I wanted to put together a small portable demo system, however, as noted below, the studs holding the elements together corroded. Maybe, if you can find a few Stainless studs, you might get away with this. Brass and aluminum create an interaction and freeze together.

[amsat-bb] Re: Arrow yagis
I have an Arrow four element 6 meter antenna that sat upon my tower for a few years and was still in great shape when it came down. It did suffer a broken element right at the boom, from a hawk sitting on the end of the element. I was able to order a replacement element at a reasonable cost and had very little trouble removing the threaded part that remained in the boom. I am very happy with the construction and performance!
