    Default Plans for a 20 Meter Mono-Band Beam?

    Anyone have a link to a plan for a 20 meter mono-bander? I would like to build one and my google searches haven't turned up what i'm looking for.

    You should elaborate a bit more about what exactly you are looking for.

    Are you interested in some kind of mini-beam or some kind of elephant gun?

    Anyway there is a lot of information on LB cebiks W4RNL (SK) site:

    you have to register but it is a treasure trove...

    The ARRL antenna book has plans for optimized mono band yagis.

    Kevin -

    There are several sources for DIY designs and tools for mono-band HF yagi antennas.
    The ARRL Antenna Handbook (or ARRL Handbook) is a good book source, that should be available at the Wheaton library.

    The ARRL web site is a good source for Antenna Project articles and Internet links.

    ARRL also has a good tutorial on antenna modeling that was written by L.B. Cebik, W4RNL (recent SK) :-(

    EZNEC is a modeling tool that you can also use.

    Another source is actually looking at the assembly and installation instructions for commerical yagi antennas,
    such as the Cushcraft 20-meter Skywalker 4 element mono-band yagi:

    Aluminum tubing and stainless steel fasteners are the key materials for construction
    (but you can substitute with other RF conductive and weatherproof materials).
    You are fortunate that your QTH is within a few miles of Penninger Radio with their large stock of aluminum masts, tubing and accessories.
    Penninger also recently purchased a wire and cable supplier.

    Other parts sources in the western Chicago suburbs are:

    WestMarine (Lombard) for stainless steel, rope and some fixtures
    Ace Hardware (Addison store very good) larger operations have aluminum tubing in a variety of sizes
    (industrial sizes as well as Reynolds DIY in screen door departments).

    DX Engineering (Ohio) and Texas Towers (Plano, TX) are 2 very good sources for antenna building supplies (tubing, etc.)

    Never forget that the restoration of an older weathered HF tri-band yagi can often be a cheaper entrance --
    the amount of work is more focused on restoration of the mfg. design.

    The Beam Antenna Handbook by Bill Orr, W6SAI, has some very good designs for yagi antennas. His 3-element 20 meter design on a 20 foot boom is an excellent performing antenna. I have had one of these in the air for well over 30 years and it is still working great.

    Thanks everyone for the suggestions. I hadn't really settled in on more specific design criteria, other then to say it didn't need to be portable. This would go on a tripod (hopefully) on my roof. It would also be preferrable if the required materials were readily accessible.

    Having just gotten into HF and digitial modes, I've found 20 Meters to be a blast. An antenna with some gain and directionality over my G5RV is what I'm seeking.

    By the way, I did look extensively at the links on DXZone. For this topic many of them appeared to be dead links.

    Thanks for all the help.

    Kevin -

    What are you doing this weekend?

    The York Radio Club has their Field Day operational setup Saturday morning -- we will have a
    variety of antennas (TH3JR yagi, R-5 vertical, etc.) and my old Novice W2AU 80/40 trap dipole antenna (still works well).
    We might have some openings for some late Saturday night / Sunday morning operational shifts !

    W9GB, thanks for the links and the work involved in posting them.
