    I like Spiderbeam products.
    I use 3 of those mast for a Bobtail Curtain on 40m. Very ligth and easy to mount.
    Been using it for several expeditions on islands of Brittany.
    I have also 2 heavy duty spiderbeam 14 ele 20 to 10 m
    In case of trouble you can buy spare parts instead of a complete mast

    I have a Spiderbeam as the top part of a 'permanent' mast.
    I removed a few top sections (as they flew around in heavy wind too much , bending under the weight of antenna wires) and now it sits sturdily on top of a 5m (16 ft) al scaffold pole which swivels up and down on an axis through two tall fence posts.

    Crosspieces fixed to the al pole and Spiderbeam enable me to rig the structure with steel cable and strong kevlar paracord; Martingale Rigging style. It's self-supporting with no guys going to the ground. I reinforced the base section of the Spiderbeam with fibreglass and resin to increase its wall thickness to 1 inch where it fits snugly over the top of the 50mm dia al pole.

    I developed the idea from pictures of homebrew wooden masts on the Antentop website, a great resource.

    Total height is 12 m (39 ft) (Of course it could be taller if one sacrificed strength and stability.)
    This wooden, al pole and Spiderbeam contraption supports a 135 ft vee doublet, a motorised satellite dish, an ADSB antenna, an active antenna, a remote atu and whatever other experiments I care to homebrew!
    It's sprayed grey to match the London skies.

    Some passers-by who've noticed the top of the mast above my roof have looked puzzled and asked if I have a ship in the back garden.:)

    I've built a 40 meter 4 SQ using the same masts. Put them up at night (40 meters after all) and down at night. Placed 4 2-foot PVC sections in cement ...2 1/4th inch so the 2 inch Spiderbeam masts slip in side. Sure better to have up all the time, but at least this way you avoid the HOA Nazi's (don't mean to offend Nazi's, LOL....quite a nightmare). The 4 SQ works quite well...similar to 2 L yagi. Granted have about a mile of radials in the ground but once they're in, you're done...the grass makes them disappear. 73 es Aloha. AH6FC

    I just got it yesterday. I have not had the chance to really try it out but I did take it out and extend it. It feels solid and all sections lock properly. One nice thing about it is the end section is hollow, so you could thread a wire down the length of the mast if desired. It looks to be about 6" longer than the Tactical Mini from SOTABeams (another good mast).

    After getting a chance to use it in the field I'll post another review with some pictures.

    The Spiderbeam folks told me they're expected in the US sometime around the 23rd of May, possibly a bit later---they're coming from Germany.

    I bought four of their 4m poles for a tri-band Moxon I'm building and they are great. All of their poles have hollow top sections so wire can go inside if desired; very convenient for simple verticals.

    I'll try to remember to post an update here about them once I have mine. FWIW, Spiderbeam makes nifty antenna accessories like insulators and Kevlar thin (1mm & 2mm) line, too.

    73,
