Vic ARDF reports and news
Looks nice! Is it aluminium? Photo makes it look shiny like plated steel.
Very nice! That looks like a very neat and robust solution.
Hex key required, or flat-blade?
Its aluminium. Haven’t found a source for copper rod yet.
Hole is 7~8mm deep requiring M6 bolt. I used a 6mm grub screw requiring a 3mm allen key.
Then I built my next antenna, I will be endeavoring to use the same tool for its assembly, either allen key, phillips head or blade head.
3mm allen key required. Hole is 7~8 mm deep. Any M6 bolt longer than 8mm is suitable.
Is a grub screw ok? Locktite?
Its aluminium. Haven’t found a scource for copper rod yet. Hole is 7~8mm deep requiring M6 bolt. I used a 6mm grub screw requiring a 3mm allen key.
Grub screws are designed for this type of clamping application. Compared to a plain bolt face that is roughy flat, the grub screw face is cup shaped and will deform the copper shaft providing superior holding power.
When I took on this task it was mentioned that previous shorting bar designs were known for their high failure rate i.e. coming loose. I don’t believe that loctite will be needed with this design.
Only the test of time will tell.
I can easily make more of these. I just need the rod diamaters and rod spacings.
