OT: T2FD

It's my premise that there's nothing actually new in the
antenna world since the '30s … except the names.

73!

Your premise would be correct... :)

Yes and no.....

Computer modeling has improved antenna design tremendously, and that is
definitely new. There are all sorts of new variations:

* G0KSC (and others) yagi designs
* Broadband aluminum half-wave vertical designs from GAP
* Broadband dipoles including the OCFD (look for an upcoming book)
* Improved baluns with much better characteristics
* Beverage on ground

to name a few off the top of my head.

Hi John,

The Beverage on Ground is not new at all, Beverage's experimental
Wave Antenna -- which came to be known as the Beverage Antenna --
w as a pair of insulated wires two miles long laid on the ground and
fed into a phasing and balancing network, a progenitor of
DX Engineering's NCC-2 Receive Antenna Phasing System.

See the transcript of of the interview of Harold H. Beverage where
he describes the initial development:

Here are some of more recent vintage.

Helical antenna: circa 1949
Cubical Quad: 1951
Log Periodic: 1957

Re: OT: T2FD

In reply to this post by Ken G Kopp

Just a couple notes:

My new two-yagi 6m array uses G0KSC LFA yagis ... not yet tested on
the air but hoping to see big improvement in eme Rx.

Tried a 480-foot BOG for 630m and did not do as well as my
inverted-L, though it was considerably quieter. Not surprised that
only having room for a 1/4 wavelength Beverage. Used land alongside
my neighbor's private airstrip as having less than 2 acres is not
conducive to owning a Beverage.

Eventually, I will try a large shielded loop Rx antenna with preamp on 630m.

I started out on 40m with a center-fed folded dipole and built many
dipole antennas early in my ham radio "career". Currently use a
80/40m inverted-V "fan style" fed with coax and balun. Works most of
AK well on those bands.

I built a 6m/10m J-pole but never worked well for ground-wave
contacts. I think a turnstyle on 10m might be interesting, esp if
phased for circular pol. or feed individually my dual Rx K3 for diversity.

Computer modeling has greatly affected VHF antenna designing.
