I recently purchased a 300 foot tower and it is painted FAA red/white. I cannot put up 300 feet because of proximity to a local airport, so will put up two 150 footers. Would you leave it painted, re
I would hang the dipole with extra wire pointing down instead of in the trees. IOW, move the suspension line on both ends toward the center. There is little current at the ends. Keep the ladder line
Nice looking amp. Do you still have it? If so, pull that filament transformer, remove the rust and add a coat of new paint. What power supply are you using? 73, Keith NM5G I have pictures of my amp t
Yes. Multiple wires from the same feed point do an adequate job on multiple bands.. Be sure to separate the wires about 2 or three inches for best performance. The reason 80 performance is different
A friend here recently purchased a home that has a free-standing tower with a TV antenna on top. It needs to be removed. Please take a look at photos on my web site: http://www.dutson.net/transfer/Ha
The base is about 2 feet per side at the base. Someone posted back privately that it is AX rather than BX. Looks to be about 45 feet to the antenna. 73, Keith NM5G Looks like Rohn BX. How high is it
You took the words right out of my mouth. I agree completely. 73, Keith NM5G Ed K4SB wrote: "As for me, I refuse to remain a member of a reflector whose administrator tolerates this." As much as I mi
Russ, and all others who replied off-list: Thanks for the information. I think this tower will do nicely for one of our club members who needs a tower but cannot afford to pay. Although there will be
John, Thanks for the info and encouraging words. I have a Rohn catalog. One responder with a sharp eye posted back that the stamp on the tower shows Spaulding, a company apparently bought out by Rohn
Assuming the tower sections bolt together, good conductivity should not depend on the lubricant used. I use plain axle grease when assembling Rohn sections. NoAlOx is used mainly in aluminum antenna
Interesting price increase. I got this quote last September: 6 pin controller plug, Part# P1091056, for $ 1.58. Pins for 6 pin (6set), Part# S8101130, for $ 1.17. Plus shipping. 73, Keith NM5G Thanks

My daughter is vacationing at her beach house near Destin, Florida and has been ordered to evacuate. She says I10 is bumper-to-bumper. Is there an alternate route back to Houston, Texas? Thanks in ad
Thanks to all who responded. My daughter, her husband and three daughters are leaving at midnight. They will drive to Birmingham to stay with friends until the storm passes. Keith ___________________
I use a 1.5" tubing cutter. 73, Keith NM5G This is good advice and just about the way I do it, although I have never tried to do 30 an hour. All I can add is that you need a decent sized iron and it
The manual warns of this problem caused by the use of rigid cast aluminum. Based on this, I would think Yaesu sells replacement clamps. 73, Keith NM5G I have cracked one of the mast clamps on my G100
Some coax is just bad news when applying heat. Same for some PL259 designs using plastic dielectric. IMO these should always be crimped, not soldered. Use Teflon connectors and high quality coax in a
Good point. I like to fill all solder holes (tip included) plus wrap the whole thing in tape to help prevent corrosion from moisture. Plus, I enjoy the smell of burning rosin. <grin> 73, Keith --Ori
phase shift for each delay line of solid dielectric coax, if the application is critical. For HF, the delay is likely not critical. From reading the ARRL Antenna Book I understand phase errors up to
