Surely you just plug the banana into the banana plug!

Nah, you plug the banana plug into the banana, of course. What you propose is akin to plug a wall into a wall-socket. :D

Is this compatible with plantains?

And under the heading "What other people are reading", we find:

How to Measure an Antenna's Signal With a Multimeter

http://www.ehow.com/how_12130900_measure-antennas-signal-multimeter.html

where they use the ohms range on the Multimeter to "Measure an Antenna's Signal".!!!!

The topic title is not so far off, it is indeed possible to measure the impedance of an antenna or other network with a multimeter.  ;)

But you need 3 of them and RF detector probes, google for impedance measurement 3 Voltmeter methode, this is from the time before impedance bridges and impedance ( RF-IV) meters, vector voltmeters  and VNAs. ( if I remember well it can also be done with 3 current meters)

I never tried it, but it is still on the to do list. But there are more ( forgotten) ways to to IV impedance measurements, like using a double ballanced mixer and voltmeters.

Ha ha ha what a topic !!! :o

and that comment from 'sacherjj' about measuring banana resistance is one solid piece of entertainment.   :-DD

may be I should start learning about how to use a DMM again ..  :P
