End Fed Wire Antennas

Over in the PWCARES Slack channel, Brian, WC4J and Dan, WA4GSD have been having a spirited discussion about end-fed half wave and other sorts of wire antennas.

It was suggested (hey, even I don’t need to be clubbed up side the head) that some of this discussion should be memorialized (since none of us have taken our ginkgo this morning) for future reference.

First up then, this handy dandy PDF of wire lengths.

Then there are a couple of YouTube videos:

And finally this little bit of information:

EFHW have better efficiency, lower SWR and is more forgiving on bands covered. EFLW tunes most bands but is 15% less efficient. You can look up more at this link on random wire.

Where might you use this? Why, in the field, like Brian did at National Night Out this week.
