Default Log Peridic 50m - 1300m

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

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.
