Re: [BVARC] [tdxs-list] Fwd: 80 Meter inverted V dipoile

[Rick Hiller -- W5RH via BVARC]

Evening Gents...for those that wish to dig a little deeper into the
wide banding issue and see what is happening out there in the contesting
antenna world, let me recommend that you have a look at the 2016 Dayton
Antenna Forum presentation on OWA's -- Optimised Wideband Arrays.   He, a
Penn State prof, has gotten some very nice flat SWR responses using some
simple parallel wire techniques.   He also looks at the current art 80 and
40 wide banding techniques, including the Bazooka.

*http://www.k3lr.com/Dayton/Dayton2016/wa3fet.pdf
*

These wide banding techniques are what is taking over the world in Yagi-Uda
design/implementation.  See another Dayton presentation (same K3LR Dayton
page)  by Justin Johnson, G0KSC.Wide banding, low noise and direct
matching all at a cost of slightly reduce parasitic gain, and slightly
reduced F/B, but an increase in antenna system efficiency due to the lack
of the lossy matching network (i.e. Gamma, T, Hairpin, etc.).   This
technique has been stareing us in the face out of the ARRL Antenna Handbook
since the 50's and only Mosley took advantage of it back then, but never
pushed the details of its' advantages...IMHO.

Another way to broad band an 80 meter dipole is to utilize a Tornado
Loading/matching coil.   K3LR highlighted this in his 2017 Greater Houston
Hamfest K3LR Multi-Multi talk.   Read about it in the BVARC May newsletter
-- Page 5 --The Radio Hotel column
   *http://bvarc.org/newsletter/201705.pdf
 *

Lots of neat stuff going on in the Amateur antenna design world in the last
decade or so.

Enjoy.73...Rick -- W5RH

[BVARC] Inverted V

[GMuller885--- via BVARC]

Help guys and Gals:
 I am looking to run an inverted V from the 50 Foot  tower. I am 
interested in what type of wire. I see that a Double Bazooka is very  quite and 
this make contacts easier. Is this true and can you please  substantiate this.

Re: [BVARC] Inverted V dipole orientation

[Jonathan Guthrie via BVARC]

I agree that the antenna seems too long.  When shortening an antenna, 
it's a good idea to take off small amounts (25mm or so) at a time.  
Also, the suggestion to fold the ends of the antenna back rather than 
cut them off is a good one.


Also, it's always good to have independent confirmation before making 
changes.  That way you don't have to go out in a snowstorm to shorten an 
antenna and then find yourself going out again a few minutes later to 
make it even shorter and then, after several snowy trips outside, 
figuring out that no matter how much you take off the ends, the antenna 
would still be too short.  (I want to say that was during the 1982 
November Sweepstakes, it was in another state, and I wasn't the one 
doing the shortening.)

As far as making it straight goes (I think that's what you're

the legs aren't too close together it won't have a huge effect
on the radiation pattern.  A right angle is probably not "too
close".  I don't believe that the radiation will be
substantially less efficient, but you may get the energy
directed in a peculiar direction.  The thing is, unless you

something up and see what you get.  If you find that you
communicate really well to nowhere you want to talk to, then
consider making changes or even trying your hand at some
modelling to see what it's really doing.

The thing to understand is that all antennas interact with the
environment that they're in.  That means that unless it's well
isolated from nearly everything your signal will go off in
weird directions because it's near the metal in your house or
a shed or a fence or whatever.  Trying to anticipate that is
of limited use, and probably not worth the effort until you
know what you're trying to do.

Better to shorten wire on end insulator and wrap it around itself than to cut 
it.   This way you keep the full capabilities of the

antenna for future use.  Also, the PSK and RTTY areas of the band are close to 
the CW area.

PS:  I will say this from a 10M rotatable MFJ 1980 Moxon type antenna to now a 
new Alpha Delta DX EE

For observations on the 20M, 40M and 80Mtraffic feels like it has 
increased 70% on all bands with stations I had not heard before or the ability 
to hear before. The 10M I will have to observe using the 10M nets coming up to 
comment on.

As far as the North/South vs East/West question goes, if you know where you 
want your signal to go, then you should absolutely orient your dipole broadside 
to that direction.  If you don't know where you want your signal to go, or 
don't yet care, then do what people typically do and put it up in whichever 
direction is most convenient.  If you've got the money, the time, and the 
space, you can always set up two of them at right angles to each other and 
switch between them, depending on which one brings in the louder signal.

As far as making it straight goes (I think that's what you're asking, if it's 
not, then please correct me) then as long as the legs aren't too close together 
it won't have a huge effect on the radiation pattern.  A right angle is 
probably not "too close".  I don't believe that the radiation will be 
substantially less efficient, but you may get the energy directed in a peculiar 
direction.  The thing is, unless you know what you're trying to achieve, the 
thing to do is to put something up and see what you get.  If you find that you 
communicate really well to nowhere you want to talk to, then consider making 
changes or even trying your hand at some modelling to see what it's really 
doing.

The thing to understand is that all antennas interact with the environment that 
they're in.  That means that unless it's well isolated from nearly everything 
your signal will go off in weird directions because it's near the metal in your 
house or a shed or a fence or whatever.  Trying to anticipate that is of 
limited use, and probably not worth the effort until you know what you're 
trying to do.

Thank you for your thoughts guys, I appreciate it!

Fantastic. This time the reply came immediately, straight to normal inbox. I 
always check JunkMail folder. Until today, no response ever made it to Inbox or 
JunkMail.
 
Thank you!

28.300   3.1 
 
the dipole is at 8 feet each side.
 
Any Advise?
