[amsat-bb] LEGO bricks vs. Wash Pins

[Henk, PA3GUO]

Dear all,

Frans, PE1RXJ, and myself have been building 
DL6WU based (portable) beams for 145 and 435 MHz. 
We mainly used them for portable satellite operations. 
Using 4 elements for 145 MHz and 7 elements for 
435 MHz we can operate AO51 "noise free".

On my website I have described how we built them,
and also the two alternative methods for mounting 
the elements onto the boom:
- using LEGO bricks (the PE1RXJ method)
vs.
- using Wash Pins (the PA3GUO method)
