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.
