I used new hex screws to replace the crappy ones that the antenna came with. If you have “fluttering” SWR, it is probably being caused by wind induced vibrations in the internals of one or more traps.
I snipped off the sharp ends because Cushcrqft was afraid that it may screw in too close to the center rod of the trap and arc. Have had this antenna up 45 feet in the air for more than 2 years here in Upstate Central NY and it is still going strong. I worked 3Y0X on it on both 40 and 20 with watts. Have owned mine for 16yrs, purchased new.
If you live in an area that is dry and not to windy then, perhaps, otherwise I would try something else. I finally got time to take each trap apart to see manuual the issues were if any.
Today, I finally gave up and removed the top trap and it’s four extra feet of tubing. The capacitors are formed by the outer shell of the can and a coaxial piece of tubing pop-riveted to the structural tubing on each end of the trap.

It has performed fairly well on the upper bands but getting it to work on 40 and 20 has been a chore. LOCATION Although the R will operate in almost any location, it will perform best if it is mounted vertically and located in the clear away from surrounding objects such as buildings, trees, power lines, towers, guy wires, antennas and metallic objects.
I’m not sure if I’m going to bother trying to fix the top trap again. It has survived a cross country move, and 5 Iowa winters.

Antennas installed with less clearance may require additional adjustments. The previous review not withstanding, T7000 use this antenna camping and I’ve had amazing cushcgaft, easily working Europe when Propagation is good Contact the site with comments or questions. If it rotated I slowly tightened more, and then rr7000 to rotate it by hand.
Even a great f7000 will suffer in poor conditions but I’m afraid the R is more susceptible to the weather out here on the Pacific Coast of Washington than most. SWRs are below 2: Also, when tightening down the stainless steel clamps you have to be careful to not over tighten and strip the threads.

A thin film of aluminum oxide apparently forms on occasion but is “scrubbed” by vibration causing the variations in electrical conductivity. Again, if you have one of these and need manula, email me.

Also, the aluminum wire that was used to wind the coil was in bad shape and looked like it had arc’d just below where it exits and attaches to the outside of the can. Got it, continue to print.
