Homebrew Wire Antennas for Portable Ops
Hello again! I am operating portable with some different wire antennas.This trip in the Black Hills of Wyoming I am trying out a new Dual Ferrite Variable 9:1 Unun with 64 feet of wire and a homebrew 80 Meter Inverted Vee. Videos coming later.
Location, Location, Location
Technically it’s the Black Hills National Forest just north of Sundance Wyoming. You can find this dispersed camping area on freecampsites.net. It’s a beautiful area for boondocking. No services like toilets, showers or electricity, but it is quiet and beautiful. Cool in the evenings and nice during the day without AC.
Wire Antennas for 40 through 10 Meters
I purchased an inexpensive Dual Ferrite Variable 9:1 Unun off ebay and from a seller that I have done businesss with before. He makes and tests his concepts prior to selling. The one I am using will handle 200 watts and tunes easily on 40 through 6 Meters using the Icom 7300 internal antenna tuner. It’s variable, so it will work on 40-160 Meters too. See the description in the link above for more information regarding it’s application.
I attached the 9:1 unun to my flagpole and raised it 30 feet. It’s being fed with 50 feet.of RG8X.
The random wire is configured as a sloper. The far end is up about 45-50 feet in a pine tree.
It’s easy and even enjoyable getting the line up using the best “Dog Gone” antenna launcher.See my previous post.
For my Elecraft KX2 I have another 9:1 unun and 49 feet of 24 awg wire. I use it in a sloper configuration too.
Wire Antenna for 80 Meters
For my favorite early morning and evening band I have a homebrew Inverted Vee. It’s approximately 120 feet long and at the center is a connector I purchase inexpensively from a Ham Radio friend (Jim, WB0KZB) long ago.
It’s up about 50 feet and the legs run East and West. I have it fed with a 100 feet of RG8X Double Shielded Coax that I just purchased. It’s a very nice run of coax and I’m sure I’ll be picking up more of it in the future.
Mini60 Antenna Analyzer
Here are some screen shots from my Mini60. I got mine on Ebay.
In this video I used a 64:1 unun and later changed to a 9:1 unun. If you have any questions please post them below.
Videos coming later on the portable setup. I will be doing more with Log4OM and a companion program to WSJT-X. That one is delayed while I’m camping.
What antennas do yous use while camping? Please post your comments below.
