Caution:: Sun damage Replacement/Purchase/Order - poly tube from MFJ and wait for back order.
- issue here is sun damage, sun cracks up that plastic.
used as a capacitor. sun damage shown.
Common Problems: sun damage
Research Dielectric Gamma Match. dielectric capacitor.
Common Problems: sun damage
Solution:
You can create one or a replacement using coax.
- replacement - use the plastic insulation that comes with RG 8 coax and use it as a replacement.
- just swap out the tube to be certain the inner diameter matches the coax outer diameter with the casing and braid removed.
- replacement - use the plastic insulation that comes with RG 8 coax and use it as a replacement.
- just swap out the tube to be certain the inner diameter matches the coax outer diameter with the casing and braid removed.
- swapping that tube out for another that will fit. Brass, copper, aluminum, will all work. Main thing is it matches the coax once the jacket and braid is removed. RG213 is likely a good size match.
Dielectric Length = 150mm
Gamma Rod Length = 200mm
