Topband: Receive Antennas

[Tom Rauch]

The start of an antenna article is posted now on the W8JI.com
web site.  The article describes how and why near field and 
induction field coupling is unpredictable, and does explain (I hope) 
how to properly model and compare receiving antennas using 
EZnec for Windows.

Over the next several weeks I'll have something up on receiving 
verticals (including the correct way to install a receive-only four 
square). I'll eventually include off-the-air sound files so you can 
listen to each antenna system described.

I've completed measurements of EWE and flag transformers along 
with photo's, and will eventually have that up also. 

I'm just finishing a keyclick primer describing what causes and 
controls keyclicks and describes a mod for FT1000MP's that has 
reduced FT-1000MP keyclicks around 30 dB at 1 kHz test spacing 
in three sample radios. That article should be up in the next week.

73, Tom W8JI
