One has to be careful to compare wares. Don't expect single vertical to beat
3 el Yagi on the roof.
Last 160m CW contest I fired up from C6AYB, using IC706 and spool of wire -
half sloper (aginst the screen door frame "ground") running from the 9th floor
hotel balcony down to a palm tree by the lagoon, perfect 50 ohm. No beverages,
just AC line noise from broken air conditioner on the next building and some
"helpers" untying the sloper. Worked very well, I beat the old LP record and
had fun getting one more confirmation for the salt water verticality.
The point is, that those limited with real estate and QTH limitations, can
have a ball going out and be a multiplier from the beach. Going LP or QRP cane
be (XYL) rewarding and not getting hernia.
I was seriously considering building traveling setup with trailer and going
to the beach (still might try low bands from VE1BY), but stumbled on this 170
acre rhombic farm on the salt marsh, can't just overlook that :-)
What the salt water does is give you 10 - 15 dB advantage and QUIET RX. Team
Vertical did remarkable job in researching the phenomena and gearing up for
taking advantage of it. It sure got my attention and looks like solved (?) the
dilemma oceanfront vs. high hills. The "infinite" plane of liquid copper sure
hogs those signals.
So basically you gotta know it, figure out how to take advantage of it for
particular contest/situation. Stand by for 64 element beechy vertical arrays :-)
