QST & Antenna Gain
 

Has anybody noticed that QST is printing antenna gain numbers again (in
advertisements, at least)?

Only the ones that have submitted the proper information as required by the
ARRL. What that is I am not sure. But I seen a comment on that in QST
recently.

Yes, that policy was updated in 1998. You can get the whole story at:

The comments were in the "The doctor is IN" column in the Sept. issue.

Wow, that's over five years ago, yet I only first noticed gain numbers
in an ad earlier this year. Thanks, Danny.

Very few antenna manufacturers have provided the required models of their
antennas.

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.

And, this isn't the ONLY PLACE for such shenanigans!! on TVRO DISH's (where
the gain calculations are Calculated, and pretty much accepted as GOSPEL,
some manufacturers added .3-.5 dB gain OVER that which is THEORITICALY
POSIABILE !!

Probably because most manufacturers don't want verifiable gain figures
published.
