    I have been looking for a versatile mast that is both durable and could be used in multiple configurations. I finally decided on the Spiderbeam mast and man do I love this thing. So far I have used it for my EFHW in an inverted V as well as an inverted L. I'd like to test it out and see how well it will support a small Yagi. I made a short video about it when I had it out on my last parks on the air trip if you would like to check it out.

    Travel size is 3ft 10in and there are 12 3.3ft sections. Highly highly recommend it.

    I have the HD version set up in my back yard, holding up my zs6bkw dipole in a temporary installation until I can get something more permanent.....
    Only now it's been out there for one full year lol, with no clamps, strapped to a piece of angle iron driven in the ground. Thru all kinds of weather, it has
    been perfect! Highly recommended.

    I love mine. I mostly use it to hoist EFHWs in my back yard, but I also printed a bracket to put my Arrow Yagi on top of it, minus the very top section. The top section would support it but it was a little scary. It would probable be fine if you guyed the mast, but I just stick mine into a heavy umbrella base and make sure it is dead vertical. I use RG-8X and velcro it to the pole at 2m intervals.

    Lots of information for spider beam vertical antennas at the DJ0IP web page, we made a 30 FT mast out of a Galvanized pipe and added the 12-meter mast on top of the pipe for the CQWW CW top band contest. The vertical was top-loaded and worked like a champ on the beach by the pacific ocean. 4D2X was the call.
    Pics if needed my email is on my QRZ profile DU3LA.

    I have the MFJ 31 foot telescopic pole version. it is mounted over a 1 inch stack with foam pack to cut down movement at the base to reduce wear and there is no not one guyed wire it bends in the high wind as its designed to do and stand straight again.
    .I placed a dab of epoxy and a 3 inch long peice of tape wrapped around each section .As for to prevent collasping at each pulled out position of the pole.....Then with 2 inch wide electrical tape.And useing my modified Ultramax to a lenght of 43 foot wire antenna with its 9:1 balun i started at the end of it at the top and wound it around the pole.Taped over the wire to its final position and starting top end .as i tighten the wire around it .Useing a roll of 2 inch started at the top and as going down the pole i taped it in one continued wrap top to bottom and wrap 3 more times and the bottum then i adjusted the 9:1 balun with all left over not much ,just under a foot and did the same wrap then tie strapped the box for balun near the bottum .Approx. ..4 foot from poles bottum to antenna wire and box, I connected one of my favorite coaxs which is LMR-240 ran it to the house to my station via a ground and tuner..each band tunes 1:1 vswr. from 6-80 m....its been there on the north west of the house for 13 years never a issue and its a fail safework horse to bring in some stations better.....out of 27 antennas around the farm here its hands down thumbs up for a winner. When propergation is crap this antenna never fails me....then next to that winner is the OCF 2-160m and then beam........I have another one used at most all events and portable set ups and it works great also for portable at most all situations......and in Maine we have bruttle weather and winds and ice and snow, rain. Each year i check out the box and connections each year there clean and dry not any never signs of corrision........And no stress on the pole either. so its a winner.............W1LWT-Lee / K1AOM-2 (APRS) google get close enough to see the antenna on the ground next to the house......

    its 40' tall. Aint no HOA gonna approve it, but rather have it up and have them tell to take it down than not even try. Go for it and let us know what happens...

    It would be really easy to lift it up when you want to use it and lower it when you aren't.

    If ground mounting its best to sleeve them. Mine was slipped into a 2-1/2 ss id pipe If I recall. It was a dairy or foodservice pipe set in gravel. Great portable but UV does tear them up over time. It will freak you out first time you get any serious wind. That probably will scare the neighbors more than anything. Only ran mine a year or so and went with a alum 43' vertical. For HOA or portable cannot be beat though.
