Item is good quality printing and looks just as depicted. One issue is that the printed collar does not sit flat on the flange of the bulkhead connector. I am making a ground plane antenna and will need to stack a couple of washers to fill the gap. It sill is a great value and a brilliant idea. I may buy several more down the line, and highly recommend this, and the seller. Shipping was fast as well.

This is a very handy little device. The VHF/UHF ground plane antenna, built on a bulkhead-mount SO-239 socket, is a classic. It has been in ARRL Handbooks and Antenna Books for half a century at least, as I remember seeing it when I was a kid, first interested in ham radio. But winds and weather can put a lot of stress on the center pin element, causing the antenna to fail. This device gives the center pin element some needed stability and the tapped holes on the SO-239 flange make extra nuts unnecessary. It meets and exceeds expectations, and is exactly what was described. The quality is very good, and should give years of service, depending on the UV resistance of the 3d filament used. It is well worth the asking price, and it shipped and arrived very quickly.

These were 3D printed for me and seller was in contact every step of the way to make sure specs were correct. Items were perfect. Thank you

To have the skill to make and put out a great product is welcomed.

Got here fast and in great condition!
