4:1 Balun Progress
Well, the balun is assembled, and tested with an antenna, though I haven't tried to load it up (yet) - I am itching to try loading the antenna with the transmitter. Receive works far better than the long(ish) wire I was using. Noise level has gone from a steady s7 - s9 to a respectable s1 - s2.
Be interesting to see how well it loads up with the transmitter.
End cap just sitting in place, so I can solder
leads to the so239 connector
Both end caps stuck on with silicone bath calk.
This stuff dries hard and clear.
I'll load it up only when this stuff dries.
Don't want any sparks!
The masking tape is only there to hold the caps in
place until the calk dries.

4:1 Balun - Continued
So, here is the 4:1 balun as it stands. (Gad I take forever to complete projects sometimes, don't I?) The balun is made up from 1.5" PVC (which is 1.5" INSIDE diameter) 3 end caps (you can see two are stacked flat face to flat face, with an so239 connector inside. The one cap has its flange facing down, forming a drip edge to help protect against water, and faces down. The other end (top) has two notches to allow the screws and wingnuts to stick out.
