Grove's Flex-tenna
 
I just built Bob Grove's "Flex Antenna." It works great!! The HF version
is perfect for those of us who travel. Just FYI.

That's nice. What are the design details? If I was to guess it looks
like a common mode antenna where only the center conductor is
electrically connected to the radio. At the coax far end from the radio
the center and shield are connected together. This would not be a good
antenna in an electrically noisy environment.

What edition of MT was that one in? I'll give it a whirl . . .

Grove is selling it for $9.95

Telamon,

From the description it appears to be simply 24 Feet

of a Single (1) Wire {Heavy Gauge} Speaker Wire
connected to an "F" Connector as the FLEX-TENNA
-by- Grove Enterprises
http://www.grove-ent.com/grovehvu.html

I think that one of those Roll-Up {Reel} Portable
Shortwave Antenna's would do about the same
as the Grove Flex-Tenna for Shortwave Listening.

You could be right about it being just a single insulated wire but use
of the word cable usually means transferring a signal from one place to
another. Complete electrical paths require two wires at a minimum
because as any engineer knows for a circuit to be a complete path a loop
forms with one wire carrying current to the load and the other wire
carrying it back to the source according to basic circuit analysis.

The description states "No ground or radials are required." indicating
that the antenna is somehow balanced and not single element common mode.

Also a plural is used in this descriptive sentence "Its vinyl-protected
wire elements allow the Flex-Tenna" indicating more than one conductor
is used but maybe I read to much into the description.

HUnchy,

Can you describe what you built in detail to
us; so that we have a better idea of exactly
What the Flex Antenna "IS" ?

i want to know ~ RHF

Mayhaps much ado about nada... the Grove dealie bears a remarkable
resemblance to the external antenna that Sony packed with my 2010.
Sony has 23.5 feet of stranded wire with a clip at one end, a plug at
the other end. Nothing else...
