I used my Hams4Hams 18m pole for the first time over the contest weekend (cqww cw 2010).
Normally I use a 10m vertical (fishing pole) monopole for 40m. I usually guy my fishing pole as it gets very thin at the top and the extra weight of wire and tape causes it to bend and sway violently in the wind.
Not so with the Hams4Hams pole. I missed out the top 3 sections as it dwarfed my house and could be seen from the front. Even so, it allowed me to mount my usual 40m vertical, but now 4m above the ground, therefore less losses. The pole is so thick and heavy duty I decided that I wouldn't need guys in this configuration so long as it was lashed to a sturdy fence post. I also mounted a 80m vertical on the same Hams4Hams pole using a centre loaded configuration.
Each section of the pole was pulled out and tightened against the lower section with a slight twisting action (no quality issues here). I made up the pipe clamps with the supplied rubber and heat shrink following the instructions closely and these worked brilliantly, serving to lock the sections securely. The supplied socket screwdriver was too small for the top section clamps but fine for the lower ones.
Small niggles aside I'm very pleased with my purchase, and this year is my highest score on 40/80m. Thanks to Hams4Hams for a serviceable product.
