I'm seeking a directional 2m/70cm antenna with substantial gain over
efficient omnidirectional antennas, such as my roll-up J-pole and my mobile antenna. I considered the MFJ 1768, but I hear that MFJ antennas aren't that well made. I considered the Cushcraft A2706S Dual Band Yagi, but I hear that Cushcraft is notorious for inflated dB claims. The Arrow II Satellite has rave reviews from everyone, but I haven't worked satellites, though I might sometime in the future. I'm not too crazy about the BNC connectors. I know that there are adaptors, but I'd prefer the convenience of sticking to SO-239s and PL-259s. Most coax jumpers you can buy have PL-259s on them, most of the good antennas have SO-239s on them, and one of my pet peeves in ham radio is the use of oddball connectors. I'm considering the dual band directional antenna from Elk Antennas (http://www.elkantennas.com/2m4405element.htm). It would come in handy for emergencies (like Hurricane Isabel), as I could point the antenna towards the repeater/net control, and if I don't need the extra gain, I can just cut back on my power output and conserve battery power. I haven't heard much about the Elk Antenna 2m/70cm log periodic, so I would appreciate comments from anyone who has used this antenna. Elk Antennas also claims that you can use this log periodic for satellite communications without a duplexer. Jason Hsu, AG4DG http://www.jasonhsu.com/ee.html http://groups.yahoo.com/group/eeham |

YOu can not get gain with out boom length. I would not think of getting an antenna for 2 meters without a boom length of atleast 5 feet. I would really go to 10 feet or longer if I was going to mount the antenna outside. Just looking at the Elk antenna I would say that it may have the close to the gain of a 3 element beam. |

For about the same price you can get a nice quad from Lightning Bolt.
