Linear polarization is standard for both terrestrial and EME communication on the 70 cm band. For EME this convention polarization EME antenna for 70 cm using four mid-sized LFA Yagis.

All the antennas in the photos cannot be considered circular polarization or polarity rotation. Circular polarization hasn't Most hams think it takes a big antennas and high power to work EME. This talk will focus on 1296 and K6CLS, Cliff is a good example of a new small station on 70 cm EME; here is his story follows: “I was thrilled to rumor that on Friday some other folks had trouble with horizontal polarization, so I rotated the antenna to Polarisation in the EME path. When an electromagnetic wave is transmitted from the earth, reflected on the moon surface, and received again on the earth, polarisation is affected by four different phenomena. 1. Spatial polarisation. Imagine you are standing on the moon, looking at the earth, and two antennas on it. EME is the pinnacle of ham radio achievement. 0.

THEORY. – Propagation, noise, antenna phasing, polarization, space object tracking, etc. 0. fully rotatable linearly polarized antennas such as the collinear array at VE7BQH which can be rotated along the x, y and z-axis or, more simply, by using cross-polarized (x-pol) yagis such as those used by K6PF and many other stations. Successful contacts can be made by two linearly polarized stations by simply “waiting it Circularly polarized microwave radiation is frequently used in EME (Earth-Moon-Earth) communication on the 23, 13 and 6 cm bands. Recently published findings [1] suggest that favorable properties of CP (circular polarization) shoulalso enable utilization on the 3cm band.

This paper describes the design and construction of a modest 432 MHz EME station for. W2PU, the Princeton University Amateur Radio Club. The antenna and receiver front end will also be used for radio astronomy instructional purposes in the university's physics department. For this project my departmental Third, Circular Polarization is the standard at 1296 and above. This means that problems of Faraday Rotation and Spatial Polarization Offset (which exist on 144 and 432 MHz EME) are not problems at 1296. You don't have to worry about being “Locked Out” by either of these phenomena. Fourth, 1296 appears to be the
