HI EME�ers and DX friends

This is to publish the home work of a 2-way  powercombiner for 50 MHz
with a perfect result.

The combiner is for Fc of 50.1 MHz but has typ. a BW of 5 MHz.

2 x 50 Ohm antennas
------------------------------------------------------------------
Measurement :

Fres ;   50.1   MHz
Returnloss :  24 dB  
Insertionloss :  0.09 dB

TNX  to  OZ3SW, Steen
-------------------------------------------------------------------

Materials :

1 ps  SQR ALU boom 30 x 30 mm  and 26x26 mm inside
 Lengh : CUT   1500 mm 

1 ps  Centerconductor  :  Ms,  15 mm� , ( 15 /13 mm , 1mm  hickness)
(cobber  is difficult to solder but ok )
Lengh :     CUT      1480 mm

Drill distance 1470 mm  -  

Holes for the connectorpin : 2.6 -- to 2,8 mm

2 ps  ENDcaps of polyethylene  ( rem. a 3 mm hole in center)

3 ps. std emale N-connectors 

Before soldering : PSE remove all fat and clean and polish.  

screws : 12 ps of M3 x 6 mm  / or M3 x 8

2 ps of bushings   . Pfte 3 pcs. std emale N-connectors
� outside. 26mm  and � inside  15 mm , 2mm  thick
placed 0.5 M.  inside  from each end
