1. [TowerTalk] JAMAICA Antenna Question (score: 1): Author: "David Jordan" <wa3gin@comcast.net>; Date: Sat, 3 Dec 2011 11:15:04 -0500; Hi Folks, Now that the F2 layer is producing some good refraction I've got a question about the NVIS Jamaica antenna. A few years ago I built this Jamaica antenna, basically four 1/2 wave wires or tw; /archives//html/Towertalk/2011-12/msg00068.html (7,899 bytes)

NVIS usually utilizes the "D" layer, IIRC. 73 Don N8DE _______________________________________________ ___________________________________; /archives//html/Towertalk/2011-12/msg00069.html (8,859 bytes)

NVIS usually works best close to the "foF2" frequency, which is the highest frequency where an ordinary wave 'reflects' off the F2 layer. The D layer just gets in the way.
