DTV DirectPC WiFi Dish w/BiQuad Feed, a Trevor Marshall Design
I took an old DTV Sony dish and ripped apart the LNB and found with a
little grinding I could screw in the right Coax mount for the
BiQuad. I just told them at Norvac electronics I was making a
wifi antenna and they knew what type of coax connector I needed
for the RG-58 and 2.5megahurts. They also said use as short as possible
piece of coax.
I also used a Hack saw to cut off about a 1/4 inch of the
front of the dish LNB so it would be flat and I could then drill and
rivet the PCB board to it.
I drilled out the rivets holding the oval dish to its mounts
and redrilled it and riveted it back on so it was then set up for the
vertical positioned feed I wanted.
I also moved some mounting bolts from their holes and added
some washers and flipped the dish over so I could then get the right
angle I needed. I then hooked up a linksys WRT54G ver2 and did a
little looking around and found four signals from somewhere. I plan on
testing it more and I'll then update this.
Ok, I added some tupperware to seal it off from the elements.
The first time it rained water collected on the bi-quad causing the
signal to dissapear without the tupperware and glue gun glue to seal it
Plugged it in and it's been up and running for the last 8 Days running
Alchemy ver 1.0.
I have figured out the
best way is to not use any type of coax connectors but to just solder
the 50 ohm coax right to the board of the WRT54G and the other end to
the biquad also. This eliminates the whole connector issue and works
better for me anyway.
I ran the coax all the way out to the biquad and soldered it on this
brother brought me a real primestar dish, so I'll make one for that
