Is there anybody out there that has used the ' Max Systems 800 MHZ protable attenna? its by Grove enterprise's. They are for handheld scanners in the 800 MHZ RANGE, The antenna, is about 6 inchs tall, and has a round plastic piece, and three metal rods that stick out from it, it looks strange, but has anyone out there ever tried one of these? I think the company wants $ 29..9 for them. I have a Radio Shack Pro-96 scanner, and I was thinking about trying one of these. Thanks let me know.
