[Elecraft] (OT) EFHW Vertical Antenna (Mike Morrow)

[Nick-WA5BDU]

The EFHW looks pretty similar in terms of matching on the full wave 
frequency (EFFW?) too.  That is, it's purely resistive and a couple 
thousand ohms.  Actually a little lower on the higher band but not 
much.  I use the same matcher for both bands.  So it's a good dual band 
antenna.

My field QRP efforts the past few years have been on 40 and 20 meters.  
I use a single 66 foot long EFHW on both 40 and 20.  It works quite 
well.  Also, my radiator is #22 or maybe #24 AWG Teflon insulated wire.

First, a multi-band antenna cannot be a “end-fed half wave” on all 
bands. only on one band, as far as I know. I’ve read many articles about 
“end-fed half wave” antennas over the years, and they have always been 
single band antennas with special matching circuits to tune them, and 
most have agreed that when they are a half wave on the frequency used, a 
counterpoise or radial is not required.
