Dear Howard W3CQH:
A 26:1 frequency range is difficult to do well. Might you intend 500 MHz to 1300 MHz? A 2.6:1 LPDA is reasonably straight forward with design information in the ARRL Antenna Handbook (including mechanical information). Use care when specifying survival of an antenna in terms of MPH. It is the equivalent Newtons per square meter (pounds-force per square foot) that is important. Several ways of describing wind speed exist and are not equal in terms of what they do to an antenna structure. Ask for pressure information. I do not recognize the "30 Lb of ICE" specification. Most often, ice loading is specified in terms of size such as 12 mm of ice all of the way around each element (12 mm of radial ice). It will help to know the task to be performed by the antenna. Tell us more. Regards, Mac N8TT -- J. Mc Laughlin; Michigan U.S.A. Home: "Howard W3CQH" wrote in message news ![]() Looking for specs on any log periodic antenna that covers 50Mhz - 1300Mhz, (Ham variety). Specs must also contain that it can withstand 80MPH wind and 30 Lbs of ICE? Thanks and best DXin. de Howard W3CQH |
