Hello Andrei, please see messages 249 etc. where we talked about it again. Yes - it has been found that during real storms the antenna developes somewhat more...
Hello Alex and others, I dont know how equal was your playing field between the Hex Beam and the cubical quad .. 2-3 S-units difference on 10m seems a bit...
Hello Con, Last long weekend (Thanksgiving Day) we had really tough weather. Wind speed was over 50 miles per hour and stormy. So, TV Rotator is 100 Kaput but...

Hi Jim, many thanks for the interest in such a test. What is your reference antenna? Yagi, Quad, ..? What else would you need? - 1.)Space: In order to do an...
Hello Andy, the 10 SQ FT is for the static windload - the matching spiderbeam data is 3.8 SQ FT, so it is very well suited. the other question is whether the...
OK Con, Should get the new rotator soon. Will keep you posted and thanks much. 73's Andrei EW1AR/NC2N ... From: df4sa [mailto:df4sa@...] Sent: Wednesday,...
hello people: I found something about so called factor: ... What the heck is K-factor? In addition to windload and torque ratings, Yaesu also offers a ...
Well, the 300 feet is the problem. I could have two poles (one is already up) 30 feet and they could be separated by 100'. The location is on top of the...
When I try to access the files I get a download of a file with the extension of (dot) E Z and my computer does not know what kind of file that is??? On 1 Dec...
Has anyone modeled this antenna in EZNEC or Win-Nec? That should provide some good data for comparison with known standards. df4sa <df4sa@...> wrote: Hi...

Hi Jim, yes of course, but thats not the point .. :-) I have modeled this antenna EXTENSIVELY in 4NEC2 Actually it would be impossible to develop without...
... I don't know about that- I imagine that the extra elements on the spider will make it out-perform the hex. I'm sure Con will have some NEC files...
Hi Jim, OK thanks for the information. Definitely looks like a very nice QTH you have there :-) But for the tests I am a bit afraid 100 ft separation is a...
Hi Con and all, I would be curious of knowing which is the performances of the Spiderbeam version Low Sunspot: Gain and F/B in eich band.... in order comparing...
... Well .. a good starting point for a 40-30-20 model is to simply double the 20-15-10m dimensions. A few adjustments in the computer model, and you would be...
Hi Alex, in the "low sunspot version", the performance on 20m and 15m stays the same as with the other versions. only 17m performance changes: since we have...
Tnx for the info Con... so, with Low Sunspot version I can have approx 1 db more and better F/B in 17 mt.... bu I've not the 12 mt... Is a good compromise :)))...
Yes exactly .. and remember it is always very easy to change back to 5-band antenna when the sunspots come up again. --> all you have to do is change a few...

This a good idea to put another set of kevlar. I just did it. Run four kevlars from the points where "fishing stuff" (forgot the name of this white plastic...
