Last post by gil - Today at 03:50:42 am
Hello. I think it would work. I have seen videos of people using multiple fishing poles to make a vertical Yagi-Uda on HF.. I see no reason why it wouldn't work as a sloper.. Not sure about the radiation pattern, but you would get gain...

Antennas / EFHW sloper array?
Last post by vy2js - December 04, 2019, 01:03:23 pm
Would there be any advantage to be had by making an EFHW sloper array?

If the elevated supports are the same height and the correct distance apart, and the feedline to the 2nd sloper adjusted in length for the correct phasing, wouldn't the slopers then act like a beam of sorts?

This also presumes both "random" wires are the same length...

Maybe it could be a "bug out beam?"

Something to play with once the snow goes away I suppose.

Anyone ever try this?

Good stuff from what I hear. I asked them for a sample to test and make a video but they declined, which I understand. I got the EU1KY model for much cheaper and so far it works fine. The Nano VNA is the new kit on the block though for $50...

Hello.
Probably, and I have nothing against SDRs, if they do have a human interface and can be used without a computer...

You cannot see attachments on this board.

This is cheap capacity meter from ebay. Works up to 12V. Power from smarthphone charger. Shows volts, miliamperes and miliamper hours. You can adjust stop voltage.

Never buy from them so no personal experience. Try nkon.nl. A lot of batteries

That's what I used, but I started too slow, and now I have trouble reaching 20wpm... You did well to start at 15, which is probably the minimum...

There's a difference between memorizing and learning. If you want to memorize the code, that video is fine. If you want to learn the code to communicate, I wouldn't recommend it. I personally learned by using the Koch method at 15 WPM. You start out listening to 2 letters, and add letters one at a time. This method worked for me and I am now at 25 WPM.
