second RAIN GUTTER attempt

HF Antennas at K3EUI

Now at new QTH (Crosslands Retirement Community) in Kennett Square - about 8 miles SW of West Chester and west of Philly.

Elevation 380 ft and room for a long wire into the woods, but not set up yet.

Trying small and hidden? HF antennas in my "garden" area (perimeter of first floor apartment).



After finding my first (horizontal)? 10 ft high, 50 ft long rain gutter was only useful on 80/40m I ran some coax to a second rain gutter.

This one (aluminum) is like the "INVERTED L" style, about 25 ft high, makes a horizontal turn, and 25 ft horizontal run, so overall about 50 ft.

Fed at the base of the vertical drop via a Palomar Engineering 9:1 UNUN and 50 ft RG8X with a choke at the

entrance to the shack.? So I allow the coax "shield" to be the counterpoise, but with RF choke, no RFI inside shack (so far).

Later I will add one 50 ft radial? and recheck the SWR.


This one tunes up very easily on 20m and 10m and might be a good 20/10m DX daytime antenna.

I was copying all sorts of 20m digi signals (including WWV at 15 MHz) with an S6 noise level.

Not so great on daytime 80m/40m NBEMS paths.

Verticals tend to pick up RFI from motors, LED's etc.


VHF /UHF pretty decent to local county repeaters with verticals ground-mounted.

VARA FM working well on 145.670 MHz.

Re: preogress with RAIN GUTTER HF antennas

 

My personal experience with using rain gutters for an antenna dates back to the mid-late 1980's when my family relocated to a new city, state and house. The new house had continuous lengths of aluminum getter, which made for a tuneable antenna, however over time the elbows and end caps and down spout transitions became great sources of noise as well as intermod generators due to joints becoming "compromised" over time with junctions becoming higher and higher resistance. Even when I bonded the pieces that were physically connected to the sections I used for the antenna, other sections still caused issues.

My rules for antennas have been based on:
Some metal in the air is better than none
More metal is usually better, as long as it can be tuned
Resonant is better than having to use a tuner; non-resonant?+ tuner is still better than none
Higher is generally better, especially non-NVIS
Copperweld wire is better than copper or aluminum if you intend to use the antenna for several years
Avoid small gauge wire (16-22 ga) for anything other than a temporary installation; winds can take them down when you need them

YMMV!

My first attempt at a "rain gutter" antenna was a 50 ft long, 10 ft high alum rain gutter.

It runs along a covered sidewalk between two buildings.

It was fed via a 9:1 UNUN with 20 ft RG8X and a RFI choke, and had an SWR below 3:1 across 80m and 40m.

Tuned up easily on the 80m NBEMS nets today and on the 40m MidAtlantic net - so OK on xmit.

However my noise level was S9 plus on 80m/40m.

so Ron coached me on how to use k3fef remote receiver (worked well).

Bummer on my local noise.


I next tried a different? 50 ft long vertical rain gutter - fed at base (bottom) with another 9:1 UNUN.

It goes up about 25 ft, then horizontal for another 25 ft.

So it is more like an "inverted L" antenna, fed at the base.

tuned up easily on 40m, 20m and 17 meters with a 2:1 or lower SWR (lucky?)


God Bless RAIN GUTTERS made of conductors like aluminum.

I put this antenna on 14.074 MHz (FT8) and stations all over the USA heard my 10W FT8 CQ.

Noise level is an acceptable S6 or so right now on 14.074 at 12:30 PM.

It won't be ideal for 40m NBEMS daytime nets with vertical (mostly) polarization and low-angle take-off.


I need to work out a better 80m/40m NBEMS horizontal antenna for high-angle signals and then figure out

a way to get rid of the background (local man-made) noise.

May try running a "long wire" into the woods (have to hide the coax underground).


I have coax into the attic - but no antenna up there yet.

Residents are not allowed to get "into" the attics? - so I need one of the maintenance guys help.


So far, this transition to a Retirement Community? has gone well.

The views are fantastic (big woods, a local fox, giant ground hog and thousands of birds)

and I can't complain about the food.

If you tested .21 and had very bad color rendition, please try the following before running .22

  • locate the file fldigi_def.xml
    on windows in the folder: fldigi.files
    on Linux/MacOS in the folder: $HOME/.fldigi
  • open the file using a text editor
    locate and delete these lines:

<!-- type: int; default: -1195853824
background color -->
<BACKGROUND>-1195853824</BACKGROUND>

<!-- type: int; default: -875174400

<BACKGROUND2>-875174400</BACKGROUND2>

<!-- type: int; default: 269488128
foreground color -->
<FOREGROUND>269488128</FOREGROUND>

the actual values may not be the same on your system.

  • save the file
  • start .22
    the colors should be close to the original default colors
  • open the configuration dialog to
  • adjust the Background, Background2, and Foreground colors to suit
  • save the configuration

Every color is configurable in flrig.? If you create a color-blind configuration I will be happy to post it for others.? You can also post the UI prefs file on the groups.io files section.

The link??is just the first one I came across in a Google search.

When I was running a project that was producing a web site for a government organisation here, we had to have the design checked for accessibility for colour-blind users. I understand that this may not be a requirement for flrig, but if you can consider it, then that will help your users.
