a quad in Finland? Not unless you make the spreaders out of pole vaulting
poles ! I had a 2 el quad which I turned with an AR-22 rotor for 3 years
when I lived in burlingame Calif. Moved to Dale City Virginia. I had to
make 4 repairs. between march and November. Working on a quad in freezing
weather is not fun even though I had a rohn 25 G 60 foot foldover tower.
the first snowstorm of the season finished it off. I loved the quad, it
performed well, I also believed that it opened the bands a few minutes
earlier than the yagi's I used to compare it to when at K4CG. We had a 2 EL
cubex quad for some MARS work at K4CG and while the quad worked well, we
lost it too after about 2 years. It was hard to work on that one as our
crankup tower was stuck in the UP position. Quad maintenance is a nightmare.
The quad should do well from the caribbean on dxpedition which is where this
post originated. I would think one of the spyder beam antennas would also do
well but I doubt either will make it thru a winter in Finland.
press on regardless
