Building a 13cm VE4MA feed:

First, you will have to steal a cooking pan of the right diameter from the kitchen.Of course, i take no responsability i you get hurt by the kitchen-tender (your wife , for example)doing that.

In my case, i prefered to buy a new one.Much safer, it will look better anyway.

The diameter should be 24cm,deep at least 6,25cm.Click HERE to see dimentions.Tnx VE4MA for the info.

Then cut a piece of 10cm aluminium tube at a lenght of 32cm.

Solder a piece of wire (1,6 or 2mm diam) in the center conductor of a "N" female panel connector,and cut it to have a lenght INSIDE THE CAN of 3.15cm.

Make a hole 4.7cm from the bottom to bolt the "N" connector. Make sure the probe is straight in all planes.

-Make a hole about 2 cm -Slowly make a edge all Cut it .Make it straight! The ring is ready

smaller than necessary. around

You will have to position the ring to fit the F/D ratio of your dish.Click HERE for the info.
