Ok so I saw this on Youtube and though I would give it a try only I designed mine for bands I actually use and not the 11 meter CB radio band. This dummy load works well in VHF 150 - 174 MHz and Extraordinarily well in UHF 450 - 470 MHz which makes it viable for 2 Meter ham, MURS, VHF commercial, marine band,, as well as UHF 70 cm ham, commercial, and GMRS use.

It may also be noted that this version may work well in the 700, 800 and 900 MHz bands also.

Also this 24 fl.OZ jar took about 1/4 tea spoon of regular iodized table salt to get the SWR readings I was getting, You can tweak the amount of salts more or less to get to your desired band of course. I was aiming for where it is now. I did further "tune" this one to 1:1 off camera by adding very very little salt at a time.

As with ANYTHING glass you should handle this with care. painting is optional but may make it more aesthetically pleasing.
