I'd suggest one or two antennas, a dipole with a plane reflector or a corner reflector. Both offer excellent bandwidth, good beamwidth, clean pattern and usually arount 10DbI gain. Go to www.cebic.com for details (and polar plots!). Just not my day today.. This is an internet security company? |

Just not my day today.. This is an internet security company? Rah futz, lizdexia kicked in... it's www.cebik.com Do check out the commentary on plane and corner reflectors. I see Much better. I need to read and understand. From what I see at the moment, the corner reflector gives me the smooth and minimal sidelobes I wanted, but not as much directivity as I'd like. Still, it's a start. |

From the site;not closely related to the thread, but to a common topic in this group: "Magical antennas. I'm not looking for magic. I'm well aware of the total BS that's out there. I have compromises I'm willing to make, and indeed it looks like a corner reflector will do what I want. Engineering is the art of compromise. |

reflector will do what I want. Engineering is the art of compromise. Corner reflectors are good, but keep in mind that it will challenging to maintain similar SWR, not to mention gain, over the multiple bands of interest. My standard question: what problem are you trying to solve? At this point it seems a bit open ended to help more specifically. Unlike other fields of engineering, antennas are one of the few where expertise is acheived by doing, rather than a mere degree. For example, Dr. Cebik is a retired philosphy of aesthetics professor. Most of what I have seen from his antenna work is especially useful to amateurs, which is the audience target of this NG. 73, Chip N1IR |

Corner reflectors are good, but keep in mind that it will challenging to maintain similar SWR, not to mention gain, over the multiple bands of interest. I'm only interested in a small frequency range. I said that I could scale designs on ham bands to what I want. My standard question: what problem are you trying to solve? At this point it seems a bit open ended to help more specifically. I want to minimize signals from off-axis, and then achieve minimum beamwidth (maximum directivity). Gain and bandwidth are compromise points. |
