Polaryzacja anten na 10 GHz G3WDG rozważania o polaryzacji anten na 10 GHz |
Conclusions • CP to CP performs worse than LP to LP by approx. 1.6dB • CP to LP has 2dB loss • No observed difference in spectral width between CP and LP • CP is of course useful to overcome spatial loss in some cases • For ultimate performance LP to LP with allowance for spatial offset is best It is expected that stations interested in working small-dish “tropo sized” stations will continue to use LP, preferably rotatable. For contests and activity days CP has an advantage. cała prezentacja http://www.eme2016.org/wp-content/uploads/2016/08/EME-2016-G3WDG-Presentation.pdf |
