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.
