Antenne


on top 2m/70cm colinear
5 ele 4m dk7zb new
HF 40-20-15-10 +6m  4ele combi

the 5 ele is a 50Ohm design 3.04m refl. to dir3
the 4 ele is parasitic coupled to the 4band HF dipole ( 9m60 long  40-10m)
 matching is perfect f/b is very good  almost too good

but no results yet on 4 or 6m  propagation is absent  as before
bands are closed

picture taken with Nikkon D70S
some dust spots internal in the camera
anyone knows where and how to clean the optics of this Nikkon?
it is not the objective lense  and not the 1/2 reflective mirror
the dust is sharp focused and always the same spots
