"or when the landlord is around to inspect" lol, indeed, that's what I like about telescopic masts. We have one mounted static to the side of a shed. Only use about 6 meters of the 12m fiber pole, and about 4.5m is up in the air above the roof. It barely moves in the top-segment, even with 110 km gusts. We've just unloaded the upper segments, sturdy as hell these poles.
I just got the mast yesterday, it was super easy to set up if you just strap it to a fence post some sort. And always guy it down, use the clamp if you want to put it up for extended time
I was never happy using 450 ohm window line with my 12M mast. It weighs too much. Even strapping it to the mast, I feel it puts too much stress on the mast. I go with 300 ohm TV twin lead for my 80m inverted V. Sometimes I use a 84' (25.6 meters) endfed and a 9:1 unun I wound. I wrap the wire around the mast as I'm putting it up. 25.6 meters of wire winds very nicely around the 12M spiderbeam. I don't think it's as good as the 80m inverted V, but when I'm operating in a crowded park, the wire vertical takes much less space.
You've the Spiderbeam mast on many portable excursions Peter and you have it set up at home. The bend in the mast was insignificant when portable cause you were able to keep an eye the bending in gusts or steady wind. Your home use shows the same bending and since you live close to the coast the wind will blow more often than not. Do you lower the pole when you are away from home or do you feel the mast can handle the extreme flexing? Squid poles are difficult to purchase in the United States and my feelings about the Spiderbeam mast is that it flexes too much to hold the weight of my G5RV. I have access to more real estate for wire antennas than you so I would utilize a 160m quarter wave 90 degrees from the G5RV with added lengths of guy rope (paracord) if I need it. I have a Cushcraft R7 vertical antenna mounted 10 feet above ground and guy it with paracord in 4 directions to prevent the wind from knocking it about too much. I seen others around the area that don't guy and their verticals bend quite a bit. Too much for my comfort especially since replacement of the commercial antenna would be more one fourth of my monthly pension check. Hi, 73 OM
Do you have it guyed near the top? I put a ZS6BKW antenna on my spider beam and the pole almost bend over, and the center point is NOT heavy, so the spiderbeam should NOT be bending as it does.
@@vk3ye Aha. Well, I thought I could do that, but the two wires of the antenna just made the spiderbeam bend over badly. It literally was bending over back on itself. I was worried that it was going to snap or break. I may have to put guy ropes on it up near the top to keep it from bending.

Peter Parker and his Spider Pole. Am I the only one who finds this ironic?
Heroic QRP webslinger from down under.
Love your vids Peter!
I love that you're not fanatical about thing that's don't matter but really know your stuff on the things that do matter. Big thumbs up.

Very nice Peter, thanks for the excellent video. The production quality is quite good, too!
Like the hose clamps with heatshrink!
Love the crows, almost thought mad max was in the area.

I like the pole. I hope to get one soon.

There antenna wires form two guys. A rope forms the third.

looks like a great setup peter!
