I believe Diamond uses gain over **isotropic** (dBi) for their rating specs... which might account for the extra ~2.2dB.
(If memory serves me the difference between dBi and dBd is about 2.2 - yes?) This is one reason to be careful about what the respective company is using for their comparison... gain vs Isotrpoic or gain vs Dipole. Mark - N9WYS -----Original Message----- From: [email protected] On Behalf Of Laryn Lohman Yup, Paul, you've caught on. Diamond must be good; very good. They've bent the laws of physics again. Diamond's 18 ft. long antenna has more <gain> than a DB Products, Sinclair, etc., which are actually slightly longer. 8.3db gain over what? I'm here to tell you, in my humble opinion, that the Diamond's actual gain over a dipole is closer to 6dbd. Laryn K8TVZ
