I always see suggestions that people simply go to their local big box store and purchase the standard THHN wire for use with antenna builds. I've attached a few photos that show the difference between that wire and the PVC-Coated, UV Resistant wire that we use for our doublets.
The THHN wire that is shown, is less that one year old in the Florida sun. The coating always peels away. It's going to do that.
The other wire I show, is over three years old in the same location in Florida.
I would much rather use the PVC wire. I do sell it by the foot if you'd like some.
As a side note, the same antenna I used in Vermont was up for fifteen years. I brought that same antenna to Florida and the wire still looks like new!
I've had several customers and radio friends, email me about this article. "Have you seen the March cover of QST?" "Have you read the article?" "What's your opinion?"Well, here's my opinion.......It's a well-written piece but honestly, I wish ARRL and/or W7SX, took a couple of seconds to do an online search for "Ladderline" before stating [...]
I'm still baffled by the emails I get from hams that see dozens and dozens of 5 star reviews on my products and still seem to focus their attention on the ONE 2 star review on eHam.net. Basically, KC9DX posted the only negative review and comment on the antenna. Now, I don't want to call him [...]
I seem to get this question quite often so I thought I would post the answer with a couple of photos.Whenever you compare items, especially in the ham community, you know you're walking a thin line. I am not speaking negatively about any particular brand. I am simply pointing out MY experience as well as [...]
What follows are excerpts from an email reply to a customer that purchased a 240', end to end, 160M Doublet with 150' of feedline.. He was reading a lot of "expert" comments on the web about how much trouble it is to tune 600 ohm feed and was a bit concerned about what he may [...]
I have no clue who sent this to me as it was labeled anonymous sender. I just thought since it came out of nowhere, it would make a nice, quick post."I bought a 40 meter doublet from K5JYB a number of years ago. I'll never use another antenna unless I find room for the 80 [...]
Baluns for Multiband Antennas fed with Open Wire or Ladder linePosted by Bob, KZ5R on November 20, 2014 At least once a week we receive a request a for high ratio balun to manage the transition from high impedance open wire feedline to [...]
A bunch of us hams get together on Friday nights to work on various projects and when boredom sets in, we often search YouTube for some fun videos. This one never fails to bring lots of laughter. Enjoy!
This is a photo I took of my 10-160 meter doublet on the morning of May 9, 2017. At our elevation in the mountains, we tend to get snow when the valley's are left untouched.The auto tuner didn't seem to mind one bit and I was on 80M for part of the morning, chatting with [...]
Many of my customers call me after they've attempted to setup their complete True Ladder Line antenna system and report problems with the tuning. This can be pretty frustrating as well as easily solved, in most situations.Many times, the balun being utilized is just not up to the task demanded of it. I hear this [...]
