Why make this hard? Take moth balls and rub them down the length of the hardline. No critter will approach. Easy and cheap. 73 Tim K3LR New to the Northeast, and all the critters that eat...well, eve
Jamie: Is this a full size vertical (1/4 wavelength) with a proper radial field? If the VSWR is 1.3:1 at 7125 KHz - what is the problem you are trying to solve? What frequency is X=0? 73, Tim K3LR --
Several guys on here have asked when this would be available. It is now ready: https://www.dxengineering.com/parts/dxe-iso-plus-2 73 Tim K3LR _______________________________________________ _________
With a good ground radial system (very important) here at K3LR - the full size 4 square holds its own - almost 6 dB of gain over ground - compared to a stack of W6NL Moxons (185 feet over 120 feet).
Best bearing - can take lots of weight. https://www.dxengineering.com/parts/dxe-tb-300 Very different from the Rohn 73 Tim K3LR I'd double check the need for a down thrust bearing to relieve the weig
Hello Gary: You can go to my website and see lots of photos of coax with ring rotors. There are 23 ring rotors here - so if you have questions after looking at the photos and videos - please email me
HI Gary Have the loop below the boom works very well here. You have to have a safe climber in place for the installation and it check out 360 degrees while someone in the shack (linked by radios) ope
Hello Scott, Yes, the end sleeves are mandatory. Do not use cable clamps as they will distort the end of the guy grip. The end sleeves are mandatory for a reason. They keep ice from getting underneat
Hello Mike: The RFI reflector is what you want. RFI@contesting.com 73 Tim K3LR Perhaps this is not exactly the venue for asking this...so direct me where it is. I have NOISE that is becoming worse al

And now they are made by Thomas Shelby - not Rohn. 73 Tim K3LR Before Rohn, they were made by Spaulding. Rick N6RK _______________________________________________ ____________________________________
Hi Charlie: I found that vinyl caps do not allow water to drain properly - having moisture in elements is not good. I do not use vinyl element caps here. Just another data point. 73 Tim K3LR --Origin
Hello Bob: How do you get the water out of your elements with caps on them? 73 Tim K3LR My experiences have been different from KK9A. Open element tips with nothing capping them, is just an invitatio
Hello Tom: I have 26 Yagi's in the air here and my experience is the same as yours. No end caps ever on the elements and no problems. Also no water related corrosion issues. Every time I am involved
HI Gary I have had fullsize 40 meter beams for 28 years. No rope, no end caps - no failures. 73 Tim K3LR I recently took down an A3s (had caps on element ends and boom ends). The traps with vent hole
HI Scott: All homebrew Yagi's here - and yes, made strong enough with Yagi Mechanical software. In the process of replacing the 40 meter Yagi's here this summer. 28 years is enough for these elements
I participated in a group buy of Polygon Rod in the late 1980s. Quite a learning curve. Even UV stabilized is only good for about 10 years - then needs replaced. Difficult to work with. I had one Pol
HI Steve: I would be concerned. Be careful. Your rod is way past its life span. Call Polygon Rod - they'll tell you - 10 years life - then replace. 73 Tim K3LR I have a mix of Polygon and Philly. The
Hello Ron: I think you are making a good choice with Phillystran for your tower installation. It is critical you follow all of the Phillystran manufacture instructions when you install it. The EHS co
Hello Ron: Please contact PiRod (Valmont) and tell them what you are proposing. That is the only safe way. All of the towers at K3LR are PiRod. Mine are not rotating towers. They are guyed as per PiR
