super tropo Saturday evening 23cm

Saturday afternoon my 23cm system was up back in the mast
The transverter is direct at the feeder of the dish.
The new 23cm LNA with the SKY67151 and 23cm 100MHz wide bandfilter
Made by VHF-design  real fb product.
is replacing the SPF5189Z  good and cheap but wide band 0-4G no filter
It seems that the 23cm receiver need a bandpass to keep all the 4G and other high level signals out
how about 5G when it is real in operation if that ever happens since using high 4G and 5G field strength in urban area's is controversial.

Left top is the feed connection the SMA relais I had to replace some N and SMA pieces that caused loss and high SWR  about 35W direct at the dish. 
PA0V  helped me,  my foot injury make me still unable to go.
We where curious about the performance of the  SKY LNA.
And if it's bandpass filter could stop the 4G breakthrough QRM.

Coincident or not, the antenna was up and  there was real exceptional good tropo happening. for this time of the year very special. iT hap…
