Enjoyed how you casually pointed out the error in the antenna textbook. Mark of a true pro.

Thanks David. Getting back into amateur radio and purchased a 102 foot G5RV from DX Engineering with “window line”.. I was going to attach the center off the tower but now will use a tree limb at about 50 feet instead. There is a 450 ohm to 50 ohm connection point. According to your video, that would be a 9 to 1 balun. Interesting. Will keep all away from the gutter and tower. A most instructive video. Thanks. 73

Finally understand electrical difference of various antenna line and their uses, thanks.

I was running a G5RV antenna, which had 30 ft of window-line connecting to coax through a balun. The performance was ok, but not great. I decided to take the balun and coax out of the equation, and ran the window-line straight into my station, connected directly to my old Palstar antenna tuner (which has connections in back for window line leads). The performance is dramatically improved! I am now sold on the benefits of using window-line.

"...(or him...these days)..." Heh heh...you rock Dave! Thanks for another great video! 73 Tony KB9A

Great video Dave, and as always, your strive to inclusiveness is a breath of fresh air. For most of us born in the mid 80s to now, a lot of this common knowledge is uncommon! This video explains a lot
-
"...or Him these days" LOL. Dave. Love ya bro!
-
This was very helpful; new technician class license here, but have been a SWL for over 60 yrs using antique hallicrafters radios. Currently a S38B with a MFJ-1777 doublet. Great, informative video, thank you so much. KO4BGD

Ladder line is great...issues revolve around how to get it into the shack! That would be a great follow-on discussion. 73 - Dino KLØS

Brilliant. I have been wondering about precisely these things. Thank you!
-
Thanks Dave. So glad I subscribed to your channel.
-
Dave, I use the smallest diameter of PEX tubing (inexpensive) to make my ladder line and it works well!
-
Wow, that was SUPER informative and explained so many things. Thanks, Dave!
-
That was a great explanation, Dave. great video. I learned a lot!
-
Fantastic information on ham radio or sw radio antennas !! Amazing stuff!! Thanks DAVID!!👍👍👍👍👍
-
Excellent explanation. Thank you
-
Thanks for the lesson Professor OG

i'm a CBer on a farm and everything outside the house just got switched over to ladderline. vertical folded dipole fed by 450 up in a 80' pine. before i had a IMAX and 150' of 8x so the boost in signal levels was DRASTIC when i basicallly put the ears right to the tree with this new feed. wasn't really into dumping a ton of money on coax to get up there. so now im working on some 1.25~ doublets so i can do a 4x array for the west coast
-
Ive been searching all morning for the very info you provided. Thank you. Trying to confirm the ohms of a homemade ladder line to determine if an old homemade trans match has the ability to handle it is a challenge. Hope you are well. 73

Dave, thanks for your very clear explanation of balanced feed lines. I learned a lot and will be using that knowledge on my next antenna build. 73 de Chris W6NOB
