Improvements to the SCT-100 Terrestrial End Caps -the first grid

IF you have an Ersa-1 from last year, you have a 100 mm aluminum grid, as an end cover and a plastic clear acrylic inside window/wire mount. 
                     The new SCT-100
We have switched to a 100mm acrylic disk, and a thin aluminum back piece that is electrically the same as the old, holds a better water seal, and the nylon ties plus clear sealer is a stronger mount. 

Remember, these helical antenna tubes are guaranteed for life. We make them as tough as we can, and also serviceable if the need arises.
