CQ Zone 3, ITU Zone 6, ARRL Section "San Diego," Age 44
VILLAGE OF LA JOLLA - A San Diego Community (QTH is on the point, far righthand side of picture)
The 2 element 80 meter array BELOW has 1.6 dB gain over a single full-size vertical (60+ feet high) and provides excellent low-angle radiation. The antenna has about 4 dB front to side ratio. It's feedpoint impedance is about 70 ohms excluding ground-loss resistance at each vertical. A limited ground radial system is required at the base of each element for VERY GOOD performance. An extensive radial system should provide EXCELLENT performance. A bit of magic turns this antenna into two close spaced in-phase fed end-fire arrays with top loading. The only thing that you need "to do" is to short the base of the second element to ground and feed the other element of the array at ground level. Unshorted, at the second element, makes this array a resonant Inverted U on the CW end of 160m. A 1:2 UNUN at the feedpoint presents a perfect 1.0/1 match on the low end of 160m. For a 40m Half Square with over 4 dB bi-directional gain, I use a 13:1 Unun at the feedpoint to deal with the high impedance.
QTH PERFORMANCE is recorded below for 160m and 75m at various locations around the world.
Additional Receive: 80m/160m 4 Square Receive Loop for diversity reception. VY2ZM (K1ZM) and K3ZM, Low Band 160m Jedi Masters, counseled me that one "CAN NEVER HAVE ENOUGH RECEIVE ANTENNAS ON THE LOW BANDS." They are right. :-)
For those that can hear me, thank you...thank you...thank you.
We also have skiing in the local mountains outside of San Diego. WORK DX, Surf and Snow Ski same day!

That's my story, and I'm sticking to it! 160m CW/SSB and 75M SSB DX are my favorite activities. I definitely consider myself a low band fan. I also participate in contests.
Work you on the bands!!!!!

More interesting links....
If you are a low band fan, you might enjoy hearing the European pile-up below on 75m. YES, I SAID 75M!!!
The below link is an accurate representation of our 75M SSB signal into Europe around 0800 UTC from K6AAX/VY2
(PRINCE EDWARD ISLAND, CANADA - IOTA NA-029). This was done from the VY2ZM Contest Station right on the
Atlantic Ocean. Thanks for all the contacts!
VY2ZM CONTEST STATION
Recorded at VY2ZM during the 2011 160m ARRL CW Contest, it is my CW contact with VY2ZM on 160m
from the K6AAX California QTH. :-) TOP BAND!
The "you tube" link below was recorded at A61BK in United Arab Emirates (Thank you, Khalid!). I was at VY2ZM's SUPERSTATION QTH on Prince Edward Island (Canada-link provided) operating 40m SSB and calling CQ DX as K6AAX / VY2 just before the March 2011 ARRL SSB DX CONTEST with 10 Elements pointed at Europe (two 3 element stacked Yagis (highest one at 170ft) and two 2 element stacked Yagis on another tower at 120ft). The pile-up was deafening. I DEFINITELY WAS MAKING SOME NOISE!!!!!!
40m SSB Pile-Up Link
75m SSB QRP DX Mobile Contact with England from Prince Edward Island (Canada) as it happened (M3SGS/M and K6AAX/VY2)
At the time of this contact, I was using a Six FULL SIZE Vertical Array right off the Atlantic Ocean and pointed at Europe from VY2ZM ("THE DEATH RAY")
