Hi John, Great work on your website and thanks for making the info and calculators available. One thing which I believe you should do... Nowhere in your calculator or discussion of the Slim Jim do you mention G2BCX, Fred Judd, SK whose invention this is. It is traditional in radio to associate the design with the inventor and it would be nice to have the articles refer to the '2BCX Slim Jim'. My 2cents.

Just built the Slim Jim for 4m and wanted to thank you for the excellent Slim Jim Antenna Calculator. Made it out of 13mm copper pipe and following your measurements within the mm the SWR was 1.5 acroos the band. Two small adjustments and its under 1.2.
Not sure how its working yet as 4m is a bit dead but always impressed with this design.

Built a Slim Jim for 70cm using your calculator.
Basic material is 4mm anodised aluminium rod 1m lenght from local hobby shop, a narrow plasic conduit box and dismantled electrician screw connector to attach in an adjustable way the N pigtail.
Compared with 1/4 wave home made groundplane.
The same repeater (HB9G)went from S2-S3 to S7-S8 . everything staying equal.
SWR of 1.5 after 20m of RG213 and a diamond triplexer. Joly good , makes me ponder about that M 160 GPX I have for 2m operation ??

Hi John,
Thanks for the tip about modifying the Yaesu MH-31 mic. It works great and much better than with the old dynamic element. Sounds great too according to on the air reports.
I hope you're having fun with your new HF amp. Nice project! Congrats!!
