[hpsdr] Mounting Hermes

[Kjell Karlsen]

Hi Berndt.

I am sorry but I can not find the PN. The one I use is made by 3M but  
nothing is marked on the roll. When I do a Goggle search I find type 8805  
pressure sensitive tape, this is probably the one I have. It is 5 mils  
(0,125 mm)tick. Several suppliers comes up on the search list.

73, Kjell
