Re: Help reading Antenna plots


 

Also, ditch the S11 Phase display and the SWR display. You can add SWR
lines on the S11 display. Add SWR = 1.5, 2.0 and 3.0 lines.
You'll get larger, easier to read displays.

To get a far better idea of what is going, please use 10 segments instead
of one. The present data is too disjointed to make any real conclusions.

The segment setting is in the upper left of the NANOSAVER window.

EDIT

I got 100ft of RG8X coax today and a gas tube lightning arrest delivered
today.

I have added some more plots after doing some testing.

First i plotted after just replacing the coax going from that 50ft amazon
stuff with my connectors to 100 feet of RG8X with factory connectors

I then moved the antenna diagonally in my yard and stretched out the
gypsy
equally on each side. There is exactly 21 1/4 inches of wire out
past the 7Mhz silver marker on the wire on each side of the antenna. Its
still only 6 feed off the ground though.

SInce I had a ton of extra coax in the garage and i was at this point
just playing with the nanoVNA i measured aproximately 19 feet of coax
and wound it tight around a cardboard tube i had in the garage that was 2
5/8 inch diameter and took another scan which didn't show any
change really.

Not sure if i should leave this RF Choke on it as i will be transmitting
and I don't know what effects it will have maybe someone could shed
insight
into why
i should remove or keep it on there.

The last scan is the entire setup from 30Khz to 1.2Ghz

The antenna is running pretty well right on the line of North to South in
my location

First Impressions with the Kenwood TS-440 i had a 59+10 wefax signal at
6338.60 that was amazing
A quick scan AM Broadcast is not that good so i don't think the low end
gonna be very useful.
A quick scan at 9Mhz up gave me at least 7 am stations i have never heard
before all at 59+10 or more although some faded out as it got darker. I
station i identified was WRMI at 9.955.00. Anywhere around 7Mhz had lots
of
chatter on side band.

The kenwood has a tuner so if anyone can give me any insight from the
plots where i may not want to try and tune or transmit would be great. I
am
really interested in all of the data modes that are out there. Flurries
and
high winds here so hopefully i get a nice day in the future to get it
higher in the air.
