It's just a stacked dipole array, at best you'll get 9dB gain. You'd get the same gain from a coax colinear, and they are LESS than half this size and about $15 to make.

quite an interesting build. i wonder, afaik the impedance of the folded dipole should be around 290 Ohm, so probably a better idea to feed each individual dipole in the phasing harness with a 300 Ohm ladder line rather than a 50 Ohm coax?

i bought 2x 3 metre 20mm oD tube plus 3x 3metre 10mm oD tube my calc is for 2x 19 element yagi for 476.9 mhz , i used the same software for DE and the recommended yagi software, all worked out well i dont have a bender, so i used 40mm oD tube , you make this look so easy though my tube is aluminum, i never thought to use copper for DE, thank you for your video ... do you have a video to make divider, phasing harness

harness guide?

Nice video!! What kind of coaxial are you using for the phasing harnesses?

@alvinacquiatan5054 2 жыл бұрын

iam using coaxial 50 ohm or rg58. or you may use rg59 so it can be hide inside the 1x1 square boom. thank you.

Sir ano pong distance spacing sa folded dipole dun sa aluminum

@sv1gsu Жыл бұрын

Hallo. What about all cables? How long they are and how many Ohms each one. Generally i want to find out all connections of the dipoles. And the distance between them and from the mast.... 73 de SV1GSU

How did you get the E dimension correct? I can't do it with the same bender

good day, you can search google for exact dimension thru computerized measurement, which i done. just gave the frequency desire what you whant, and they will gave you the diagram. thank you.

mas nice ang 4 loops, or folded dipole, kung mi budget i prepare 8 loops.

That soldering iron isn't really powerful enough - the heat leaks away into those big chunks of metal - I'm surprised that you managed to get a finished joint - personally I wouldn't trust any of them to be good 'uns.
