The M6MRP "Stiff Wire" Slim Jim Antenna for 2 Meters Hi... I would like to add my build
experience for those interested in the Slim Jim antenna and the cost is
NOTHING. Just a little time and fun is required with great
results.
I came across this web page on
Hamuniverse.com when I was looking for a quick and easy VHF home brew
antenna for when my VHF/UHF beam comes down from the roof for
repairs. It has taken a beating with the recent high winds here
in the north of the UK.
I live a long way from any active
repeaters or internet linked nodes so the antenna I need to build has to
be quite powerful for my needs. My rubber duck antennas on my
HT and FT-817ND are not usable at my QTH which is down in a steep river
valley surrounded by trees and under a lattice of overhead domestic AC
supply and telephone wires.
Other antennas I have also tried are a
mobile 5/8 wave on a ground plane, a home brew J pole and small home brew
dipole all with less than favorable
results.
After reading on this site about the slim
jim antenna and other peoples results, I decided to knock one
together out of scrap material from around the house and give it a
try. "FANTASTIC" were the end results is what I say about the slim jim antenna! See photos below of this very simple and easy project and it is cheap!
I set it up indoors strung from the
curtain rail (shown above) in an upstairs bedroom and I have
respectable and very much usable results compared to all other antennas I
have tried.
My build took 20 minutes using an old length of coax, some bailer wire, soft plastic tube as spreaders, two felt tip pen tubes as 2 inch end spreaders and a choc block connector for the coax connection and swr tuning slide. (It was usable at 1.4:1 after build, set for 4" from the bottom as per directions for the Slim Jim Antenna project on this page.) Cost for
build £0.00 using all scrap materials from around the
house!
I will be building a more robust version
for the roof as I am so impressed with this antenna and I would recommend
anybody looking to build a 2m antenna to improve the RX/TX of an HT for
holiday or base use to give the slim jim a try even with semi rigid (stiff
wire) like I used.
The slim jim antenna is really good and so simple to make. Thank you and
have fun.
