Rick is correct. Any easy way to see this is to use Dan, AC6LA's, TLDetails program. Wes N7WS On 4/26/2020 1:38 PM, VE6WZ_Steve wrote: Rick, We are talking about sweeping the feedline and looking at
I agree with Dave. We had a similar discussion about this (using monopoles) nearly 20 years ago in the rec.radio.amateur.antenna forum. I wrote a little paper at the time; I see it's available at:

There's some misinformation here. Rather than reinventing the wheel, I will suggest reading the EZNEC help section: "Stepped Diameter Correction Overview". Wes N7WS Excellent point - tapered means
If you have a proper balun at the feedpoint, there isn't a "hot end." It's a balanced dipole, until it isn't because one end is closer to the ground than the other, of course. Wes N7WS On 6/13/2020
Indeed, that's why monopulse RADAR antennas determine angle information using the delta channel nulls. Wes N7WS One thing you also need to be aware of when working with nulls is that the slope of th
My RX antenna is my TX vertical too. Conventional wisdom says you "have" to have a receiving antenna and a vertical TX antenna to work DX. I worked my first 80 countries or so with an inverted-vee,
Why is the dipole resonant at 3.8? Are you using it there or only on CW? Wes N7WS I have a 40 meter beam, and a rotatable, loaded, 80 meter dipole on the same mast, a few feet above the 40 meter be
Okay, I'll think about this some more. Note to others commenting, Steve is worried about interaction between separately-fed antennas, not harmonic suppression. Wes N7WS 73, Steve, N2IC -- Why is the

I second DX Engineering. I have not looked inside one of their switches, but based on examination of some of their surge protectors, I would not recommend Alpha Delta. Wes N7WS 73, Keith NM5G I am
I suspect this was intended to go to the reflector instead of just me. Yes, since DX Engineering doesn't actually manufacture switches, I was talking about Alpha Delta. I previously (2017) bought tw
I probably told you about them. Iota is here in Tucson and eons ago I moonlighted for some of the principals at another startup company. I've also used their stuff in my RV and have recommended them
In my youth I spent some time working in the automotive machine shop that my dad ran. Disk brakes were unheard of then, so everything was drums. (I'm dating myself).. In addition to the asbestos du

Roy was quite the guy. He spoke to our Southern Arizona DX Association a number of years ago about his antenna farm. Quite remarkable, if cringe worthy. http://w7yrv.blogspot.com/ Wes N7WS ________
