20M Yagi Ready for 3Y0Z

It’s only a couple months until the biggest DXpedition perhaps ever takes to the airwaves. My home brewed 20M yagi is up at about 30′, and when 3Y0Z fires up, I’ll have this Spiderbeam push up mast up to just over 40′. The best combination of gain and front to back seems to be at about 40′. This is great because my mast goes…

Offa Rex

This is an amazing and “hauntingly beautifully” album. We had a fantastic bike ride today – 35 miles, which is just enough for me to be considered “serious”. All along the ride I was hearing this album – with several songs taking their place in my mind as I looked at stunning fall colors of yellow, gold, red, orange, crimson, rust and anything else…

This Weekend is 20M Weekend

I have a really nice home brewed 2 element 20M yagi that is only up barely 30′ and which hangs over my garage roof. When I put it up, it confirmed something that Tom, N6BT mentions in his excellent book, “Array of Light”, and that is that an antenna over a roof will be affected by anything in the house that is metal, and…

The RFI “Sleuth”

In the last year I made two changes to my antenna farm that introduced RFI issues. Not RFI in the shack, but RFI that I am causing that: Only on 160M I all of a sudden cause my Trane Heater blower to turn on and off for short periods – just enough to blow cold air through the house and make fan noise Turn…

3Y0Z: The Biggest Deal in Years!

There will be one part of the day where the US West Coast will have a major pipeline to 3Y0Z – 23z UTC: So, you better believe that I will get my 20M home brewed 2 element yagi up 20′ higher! It should last a couple hours each day, and if the team says “West Coast Only”, then we should all get in their…

20M: Up, Up and Away!

Tomorrow I will get the new mast in place so I can get the 2 element home brewed 20M yagi up to 50′ from 27-ish feet. The model is only sort of correct. I will end up with 12 dB F/B and 4 dB gain, and a lower take off angle

Preparing for 3Y0Z

My homebrewed 2 element 20M yagi is not up high enough, and as a result of last weekends antenna work, I now have a spare Spiderbeam 40′ pushup mast. I can put this on my back deck and then get the yagi up ~50′ since the deck is 8′ off the ground. Its only 27′ up now.  I also took down that center element…
