Very few antenna manufacturers have provided the required models of their antennas. 73, Ed Hare, W1RFI This may be an ironic inversion of the condition we had years ago, where antenna manufacturers claimed all kinds of gain numbers for their products because they knew they were essentially unverifiable. Now, with the new policy in place and a better means of verifying antenna gains through modeling software, it is almost as if no one-- or, rather, very few-- want to step forward and put their claimed antenna gains on the line. Interesting. It looks like ARRL has done its job well, at least to weed out the ridiculous numbers from the rest. Al W6LX |

And, this isn't the ONLY PLACE for such shenanigans!! on TVRO DISH's (where
