I have been contemplating building a Moxon Yagi 40 meter beam for a long time and I need to get started with the project. The bottom line is I need a strong boom 30 foot long. I'll use a boom truss b
How effective is a vertical dipole? (Does not depend on a ground return.) Sure, height above ground might change the pattern. Lee, w0vt http://k9yc.com/VertOrHorizontal-Slides.pdf Vertically polarize
I'd be curious to know of some inexpensive way of supporting ladder line or open wire line along a building. I realize The Wireman has an insulator for tower mounting but the things are over $3.00 ea
I think maybe I have found out on my own what might work. Check these out!: http://www.fleetfarm.com/detail/powerfields-extended-wood-t-post-insulators/0000000035291 Lee, w0vt On 8/12/2015 10:00 PM,
Have the relay spacing around an inch and the contacts good for 5 amps. Don't hot switch when energizing the relay. You should have no problem with your idea. Grounding or undgrounding the unused ant
I've used aluminum fence wire for antennas for years with never a problem. I've used it from #17 to #10. Works just fine. I hook it to copper using electrical wire nuts squirted with anti oxidant gre
I took my Novice test the same day Terry Sterman took his at the Milwaukee Court House back in 1953. We were both very young teenagers. Terry became WN9DIA and I became WN9DRC. Terry started his ham
I saw a very sad statement made yesterday on one of those Chinese vhf/uhf reflectors. The ham was so excited as this was his first field Day. (He was using a $35 Chinese vhf/uhf handi talkie!) This i
When you use open wire line into a balanced matching network you don't worry or concern yourself with a "little stretch". In fact not even with a "lot of stretch". Lee, w0vt _________________________
I can tell you horror stories about why what you say is BS. I was a sales guy for a very large company. My company was the market leader in our field. I eventually retired in this job and had a very
Has anyone on here been using a MFJ-998RT Auto Remote Antenna Tuner? If so, I'd like to hear what you think of it. I am considering buying one as the remote concept and 1500 watts capability intrigue
Woa! I just think I found a deal breaker about this tuner. It looks like there is no inside controller for the RT version! I think there is some sort of control function at the remote tuner itself. S
Some time ago I decided I wanted to build a full size 40 meter Moxon Yagi beam. It never happened. Right now I've gotten Cold Feet to the project. I'm beginning to think the beam would be just too he
I might add, I suspect one could adjust the matching point to 50 ohms bye using a delta connection running out on both sides from the center of the driven element provided the center point would give
Looking at the Mini MOXON design, I see the boom length is around the standard .2 wavelengths for a driven element and reflector. I know for regular Yagis, beyond .2 wavelength you don't get much mor
What is the name of the US company that sells saddles like this? I once knew but lost the info. Lee, w0vt 73, Roger (K8RI) http://www.stauff.com/index.php?id=4022&L=1&MP=3979-3980 The 2" and 3" U-bol
I don't know what power level you are thinking of running but I have seen a couple fires from full limit power. The last was at W5MP. He was using his L-4B amplifier feeding commercial Ladder Line.
