Dish tune- and load capacitors

With the kind help of Mario ( PD0MNI ) I got me a set of brass tune and load capacitors.
As can be seen in the construction drawing, stationary plates were
foreseen. After calculation of the necessary capacity I considered
to leave the stationary plates out. Tune and load capacitors should
have capacity enough (ca 3pf for tuning and 6 pf for loading).
The load capacitor is also the (coaxial) outlet of the amp.
At the end of this a N-type connector is mounted.
Teflon isolation is used, to withstand large RF-current and reduce
losses.
