I have a 350 foot - 4" diameter conduit that I have fished wires through several times. I have many many wires in the conduit and I would never consider pulling them all out just to add additional wi
Electrical wire makes a great pull "rope". Don't forget to use a generous amount of pull lube. Thanks for all the replies. I went out and got a 125 foot fish tape at the Home Depot. It went completel
The K9AY outdoor box has a manual switch for changing the termination resistance. There are three settings, one for 160m - 80m and compromise. I'm not sure how critical these values are and there is
What are you not satisfied with - the SWR curve? I have two 20DX-6 antennas with 2:1 SWR at the lower band edge but they play very well. If I ever take them down, I'll try to improve it, but it's not
I am currently building several antennas which will be installed in a corrosive environment and I'm looking for bolts to clamp the boom to the mast. DX Engineering sells SS "U" bolts along with an al
If you are referring to I-Beam anchors Pyrod sells them. I believe K5IU also sells them. They usually require a large concrete pad. Looking for any info on how to install "Above the Ground" Vertical

Hello TT: About a week ago I placed a request on towertalk seeking stainless steel U-Bolts for mounting antennas on my tower in Aruba. I stated that I purchased some from DX Engineering http://www.dx
I had a new septic system installed a few years ago and the backhoe clipped by 4" PVC conduit. Mine was broke all the way around, but the wires were unharmed. I removed the jagged edges and cut anoth
If you intent to load your tower up with antennas it's probably less expensive to rotate the whole tower. There's a lot less rotor wire and maintenance when using a single rotor. The rings do give th
That sounds like a #10 fender washer, although my catalog shows 1 1/4 max. od. 1/4" washers have a 9/32 hole. Perhaps your washers were mismarked? Bud Another thought. Consider using 20d Galvanized N
My Rohn catalog dated 1987 states that anchor alignment has a tolerance of plus or minus 0.1 degrees. If you have a 100' tower with an 80' guy radius your anchor location would have a tolerance of pl
Without knowing your application it's hard for anyone to make suggestions. Do you intend to have a mast with antennas? Are you turning the mast with this ring? If you do have a mast and another rotor
It is possible to use a smaller guy radius than 80% if the anchors, cable and tower are properly designed. A 100' lightweight aluminum tower is not going to be able to hold much, maybe a VHF antenna.
I have many 600 foot runs and I use 8ga house wire to minimize voltage loss. Avoid peanut flavored wire. John KK9A Is anyone using this rotor with a relatively long run of cable ? I will need to use
I have used plywood forms for most of my guy anchors and this worked out pretty well. The forms made it easy to calculate concrete usage. Make sure that your forms are strong and well braced and that
