*Subject*: RE: [amsat-bb] Formula for antenna polarization loss*From*: "Ron L. Sparks" <rls@xxxxxxxxxxxx>*Date*: Sun, 21 Jan 2001 20:15:18 -0600*In-Reply-To*: <Pine.SOL.4.10.10101201936230.5404-100000@leto.ece.msstate.edu>

If I interpreted the formula right (had to move the first close paren to the end) it would be: Loss (in DB) = 10*(log base 10(cos(theta))^2) This says that the loss at 45 degrees is only about 3 dB. If that is right then the crosspolarized yagi's make sense. Is that the correct interpretation?
