This replacement loop antenna performance hopefully will be promising. But I won't really know for 24 hours of SID monitoring to determine if the antenna's 80 wiring wraps will pick up VLF signals and measure up to the Stanford quality rating score; a lower rating is preferred of course. 

My old broomstick loop antenna was achieving a Stanford quality rating score of eight, six and as low as five on the quality rating score. 

I'm monitoring three stations: 
NAA (Culter, ME) = 24000 kHz, NLK (Jim Creek, WA) = 24800 kHz and NML (LaMoure, ND) = 25200 kHz.

There is a PVC pipe the loop antenna pole mount slides into, and an adjustment screw which allows me to rotate the antenna for better VLF tuning and lock it into position. 

To protect the wiring connectors, I used electrical tape, a freezer sandwich bag, all wrapped in a bicycle rubber inner tube, and protected (covered) with 3M all weather proof tape. 

Worked fine protecting my old broomstick loop antenna.
