Re: Topband: K2AV Counterpoise

Hi Dan, I can see where you've reached your conclusion, but your comment that "Rudy seems to say..." is a good qualifier. Let's get back to basics, say with a classic 1/4 WL vertical. The theoretical impedance against an in infinite ground is 36 ohms. From free space modeling, one quickly

Topband: FW: 160m Vertical Ideas?

Is it possible to run a 128 foot wire to the top of the 89 foot tower, then across to the top of the 102 foot tower? If the towers are 35 feet apart, that gives you pretty much a 160m quarterwave. As many radials at the base as you can manage, would be a rather good (mainly vertical) aerial.

Topband: 160m Vertical Ideas?

Greetings! Trying to figure out my scheme for 160m. I currently have three crank up towers about 35’ apart from one another. One cranks up to 106’, the next to 70’ and third, to 89’. I figured I could shunt feed one of the taller towers and call it good but I’m concerned about interaction

Re: Topband: More on radials

Hi Gary, This is the first time I hear about the DOG. Would you have online references about it? I'll Google it, but if you have goods ones handy, please send them to me privately (unless others here are interested as well). Thanks and 73. Vince, VA3VF On Fri, Oct 27, 2017 at 10:00 AM, kd9sv

The sad part is that most, not all, don't care if they hobby dies.  They are simply in it for themselves. On 10/26/2017 11:32 PM, WT2P - CJ Johnson wrote: (this is a non-topband related matter but I feel I must chime in -- mostly because if you scare away the next generation of topbanders,

Re: Topband: More on radials

About 20 years ago I did the DOG (dipole on ground) experiment) at my northern Indiana location. Many others have likely done their own DOG tests but my results were that the dipole needed to be shortened by nearly 50% to still be resonant when lying on the grassy soil at this location. Based on

I agree! This thread about asking the moderator to stop the other thread has run its course. I hope we won't have a thread now asking for the thread that asked for the other thread to be terminated started. Enjoy the nice discussion about radials. 73 de Vince, VA3VF On Fri, Oct 27, 2017 at

Re: Topband: Shortened Radial Experiments

As a practical application, the "Battle Creek Special" is configured with shortened radicals; 30 X 60' for mni years now.   It's success is well known. We found, that when 1/4 wvl radials were furnished, DXpeditions often did not have space for deployment.  And used only a few of the radials

Hi All Despite being a keen 160m DX-er for the past 45 years, I've just finally joined this Reflector ! So I'm looking forward to reading 160m related posts. What made me decide to join was reading through the 160m receiver comparisons - very interesting. I stayed with my FT101E (with 250Hz

Re: Topband: K2AV Counterpoise

This entire thread has had some really good stuff here and there on radials. Nicely done, gentlemen and a really good discussion. :>)) Is there a reason why it will now get buried in the archives with a searchable subject of "Topband K2AV counterpoise" ? ROFL. Or was this a thread hijack back
