All: I have a flat-top doublet approximately 100 feet long with it's apex 30 feet above the ground. It's fed with 300 ohm ladder line. I also have a 20 meter, 5 element mono-band Yagi that's twice as
Mike: That's a good suggestion. I'll give it a try and report back if there's any interaction. Thank you. Tony From: Tony <dxdx@optonline.net> To: towertalk@contesting.com Sent: Wednesday, March 2, 2
All: I'm interested in a home-brew receive-only loop to cover 160 / 80 meters and was thinking of using multiple turns of wire around a 6 foot diameter PVC frame with a motorized capacitor. I have a
All: I'm in the process of getting materials together to run both RF and AC service cables from the house to a shed. I was going to install separate schedule 80 PVC pipes, but before I do, I was wond
Well that ends that idea. Thanks Al Tony Sent from my iPhone All: I'm in the process of getting materials together to run both RF and AC service cables from the house to a shed. I was going to instal
All: I'm looking for a low-cost free-standing crank-up capable of handling a couple of VHF/UHF Yagi's as well as an azimuth and elevation rotor - something in the 30 foot range. I thought about a hom
All: I have a multi-band end fed (see below) that I'd like to try on 80 and 40 meters. After reading W8JI's notes on 1/2 wavelength end-feds, it's clear that a counterpoise is needed; without it, the
All: Anyone have experience changing the bulb on a Yaesu G-2800XA controller? A web page with illustrations would be helpful. Thanks, Tony _______________________________________________ ____________
All: I use an end-fed half wave for portable work and was wondering what the most effective way would be to reduce the ingress of feed-line noise? I've compared it to a resonant center fed dipole in
All: I have an 80 meter dipole fed with 300 ohm ladder line that needed to be moved to a different location. The antenna is 110 feet long and the ladder line is attached to a DX Engineering 1:1 tuner
Mike: I expected the outcome you describe to some extent. Unfortunately, my antenna tuner has limited range so I'll need to modify the feed line length to bring the SWR down and hopefully retain the
All: I manged to tweak the length of the 300 ohm ladder line to where the SWR dropped to 1:1 in the middle of the 80 meter band. The SWR decreased on 40 through 10 as well so I can now use my limited
Don: I'm aware of that. I just needed to address the limited range of my auto-tuner and trimming the feed line allowed a more favorable impedance. Worked out well. Thanks, Tony ______________________
All: Adding stack of mix 31 cores at the feed point of my end-fed half-wave portable antenna eliminated the noise I was picking up on the feed line. The single-core did help, but the stack does a muc
All: I use a 33 ft. fiberglass pole to support an end-fed half-wave dipole which I use for portable work. The problem I'm having is that the pole bends considerably under the weight of the 66 foot 14
All: The indicator on my Yaesu 2800 rotor has stopped working. I put a Yaesu 1000 control box in line and the same thing happens. I have an Array Solutions lightning protector in line and was told it
All: Following the guidelines below (thanks Chuck) I found that the resistance between pins 1 and 2 and pins 2 and 3 change very little when spinning the rotor stop-to-stop. The other values are fine
All: Not sure if this is the proper procedure, but the last time I replaced a Yaesu rotator on my U.S. Tower heavy-duty crank-up, I used the bolt that's built into the tower to hold the mast in place
