Great Idea with Design Flaw  Time owned: more than 12 months
I've owned the 40-foot version of this mast for over fifteen years and it has seen a lot of use, but never at 40 feet! The aluminum tubing is of premium quality and the telescoping fit is excellent.

The design flaw is in the method used to lock each section of tubing in place. The hemispherical protrusions that pop into mating holes on the next-larger tube appear to be stainless welded to a "U"-shaped leaf spring which itself appears to be cadmium-plated spring steel. The leaf spring blocks the inside of its tube. In order to allow each tube to retract into its mating tube, these springs must be located quite close to the end of each tube. That is the reason for the way-too-short 4" overlap. Also, the stainless hose clamps that are included are there to function as stops to prevent the leaf springs from being driven out the bottom of their respective tubes when the tubes are nested. If you get one of these masts, make certain the hose clamps are in proper position before retracting the mast. A better way to lock the mast sections in place would be with quick-release (or "pit") pins through holes positioned to give at least twelve inches of overlap.

I ended up buying a new set of hose clamps (so the originals could stay home and do their job), and I use three feet of overlap for the top six mast sections which gives a total mast length of 24 feet, all double wall save the bottom three feet and, of course, the top three feet. Configured in this manner the mast is quite stiff.

The 2" diameter bottom section fits very well inside 2" nominal diameter galvanized steel pipe, and using a 2" floor flange, some wood, and some big tent stakes a very sturdy base can be built for under $30.

K7WZU pretty much nailed it; I wanted to add a bit of detail and some of the things I did to make this otherwise really-good mast more useful. Mine still looks almost like new, even the cad-plated springs. It's too bad the design of the locking mechanism so badly compromised this slick idea.

Save your money  Time owned: 3 to 6 months
These masts are simply too flimsy to be of much use since they barely support their own weight. Very unsuitable in any kind of breeze OR with an asymmetric load without the use of guys. Tried them in two field deployments and gave up.

Save your money and buy a used 35 ft surplus poleset instead! They are MUCH more stable (and safer!).

Good quality but requires guys.  Time owned: 0 to 3 months
I purchased and installed the 'Rover' 26 foot 'portaple collapsible mast' with big foot and snap on antenna mount. When initially extended and installed in the big foot, I found the mast wobbly and unable to stay vertical even without an antenna attached. I expected more rigidity from the mast but found it really could not handle any antenna load without leaning over unless guyed.

The problem, in my opinion, is the 4" overlap in tube sections is way too short for any reasonable structural moment connection when used in a portable condition without guys. When you multiply this times seven sections, it is highly unstable.

In my installation, I added 14 circular pipe clamps (like they use on radiator hoses) and reinforced the aluminum at the top and bottom of each section joint overlap. I also increased the overlap between sections to 8", using a pipe clamp to support the joint rather than using the spring clips in the holes that come with the mast. With this modification, the mast became fairly rigid when extended but reduced the total height by 24 inches. When installed with the included guy bracket and user supplied guys, it is rigid and will handle a sizable wind load.

I have installed an A-99 verticle antenna on it and it is working fine with no deflection in the wind. I would highly recommend that the manufacturer increase the pipe section overlap to 8" and they will have an antenna that will work as a mast without the use of guys.

The big foot base is well made and solid but unpainted. The snap on antenna mount works fine, and the pipe clamps that come with it do a good job of reinforcing the aluminum but the 4" pipe overlap is the weak link that limits an otherwise good product design. You must use guy ropes to use it as it is built but it has the potential to work well as a true un-guyed portable. It is a great idea that with a bit more engineering could become a reliable portable self-supporting mast under light wind conditions.
