ANTENNA CLOSE-UP

MY SIDEBAND ECHO OFF THE MOON

EME

This is my Earth Moon Earth (EME) array that I use for communicating with other Ham radio operators all over the world by means of bouncing radio waves off the moon. The path loss to the moon and back on 432MHz is very high, 261 to 263 dBs. Large antenna arrays, high power levels and a very low noise preamp are required to make the trip to the lunar surface and back to our planet. The distance to the moon and back is close to a half a million miles taking about   2.5 seconds to hear the echo. All the antennas and low noise preamp in my array are homemade. I found the design for my antennas in the ARRL Handbook. The design I chose was the FO-33, a high performance yagi designed by K1FO and K3IPW. The FO-33 antenna has a gain of 20 dBi with a 3dB beam width of 18 degrees. I am using 8 of these super yagis in my array to give an antenna gain of 28 dbi or 631 X. With 1500 Watts out of the Lunar Link LA-70B Amplfier my EIRP is close to 1MW making my station close to the output of WVIR claiming to be the most power TV station in Virginia. I am using the M2 Orion RC-2800 rotor to control the azimuth of the array. To lower the antenna array for easy maintenance, I am using a Voyager VH8-30 Hazer Winch transit system. The VH8-30 allows the whole system to be serviced from ground level with the aid of a 12 foot step ladder. With this setup and the help of K2VJ, I was able to place 3rd in the 1998 ARRL INTERNATIONAL EME CONTEST in the Multioperator 432MHz division. I missed the 1999 contest due to moving to a new location. In 2000 with the help of KR4V, I placed fifth. In 2001 with the help of KR4V, AD4TJ, and N4BCC, I placed third. In 2002 I placed fourth, and in 2003, with the highest score so far I placed third.  In 2004 and 2005 with help from my friends, We placed fourth again. In 2007 we placed 1st. In 2008 and 2009 we placed second.   There is a LOT OF EFFORT AND TIME required to get even to this level, and I am very happy just getting this far. Just being able to hear the radio signals that are over 2.5 seconds old bouncing off the lunar surface is a thrill that most hams will never experence and is quite a thrill all by itself.
