Hello to you all, Today I finshed my spiderbeam and its working fine I think !! I have lots off influence of trees and nearby obstructions. When I pushed my...
Hello to all I have finished to built my home made Spiderbeam 20 17 15m for a few days but I get some trouble to tune it. I respected the sizes of origin, but...
Hello Dan, congratulations for building up your homemade Spiderbeam. I think your problem can be solved if you used the CQ532 and if the lengths of reflectors...
hello RENE Thank you so much for your fast answer Indeed I used CQ232 and at the beginning I took as the mesurement of the driven elements the sizes"A" of the...
Hello Dan, sorry but this is not an easy question to answer. I know that several people tried to use separate feedlines (one for each band) for the 20-15-10m...
Hello con Thank you for your answer I well took note on your considerations of separate feedlines for driven elements. Currently I make measurements directly...
Hello all! After two months active dx-ing and some contests, spiderbeam lost performance in RX. I really don`t know what is going on. I made A/B test comparing...
Forgot to tell you, I make QSOs with 3B7C almost 20-17-15-12-10m cw/ssb/rtty with spiderbeam and PA (500-700W), maybe RTTY with that power destroyed something?...
Hi Zoran, check your coax connectors for oxidizing, cold soldering or loose contact. When you TX or measure with Ohm-meter you apply volts, which pass easy...
Hello, my 5band HD beam with addition of 30m dipole is on the air now! It took me about a week for preparation and 5-6 hours for assembly and to put it up on...
... Yes, separate feeders for any close-spaced multi-band antenna can be a challenge - my homebrew spiderbeam replaced a Force-12 C-3 converted to separate...
I was thinking, Is it just possible that I could take the driven element of my Mosley TA-33M which has the 40-meter traps on it, and make it one of the X-arms...
This question is on behalf of Roger, GM4PMK (not a member of this group) who has a 12m Spider-pole vertical on the Isle of Mull, EU-008. I have posted some...
Hello to you all, While my spiderbeam is not really fine tuned, see my site: http://pa2jjb.texel.com/fotosvdweek.htm but worked with 15 Watts KA3ARF and...
Hi Boyan! Is that single element on 30m or ? Can you write us more details about project? Thanks for info about my problem with spiderbeam. 73 de T96C, Zoran...
Ian/Roger During the heavy gales last month on the Summer Isles I had my pole guyed at the 4th and 7th sections using four guys at each height. ( I use cheap...
No - but I do know that Walmart sold me a bunch of hose clamps which had plastic knobs which could be turned by hand, and thus not needing a screwdriver. Ive...
Hi Zoran, I would second that .. Look for ANY oxidized connections. The hardware used in Spiderbeam balun is all stainless steel, so there should be not a...
Hi Jay, I think in theory it should work. I dont know about the SWR though. As you may have seen by other comments on this mailing list, we are all happy that...
Hi Jim / Ian, yes I would second the notes by MM0BQI - if you guy the pole at those two levels it should withstand the strongest winds. Most of the times I ...
Forgot to reply to this as well - dont worry about 500-700W RTTY, this would not matter at all. We have tested the antenna with 1500W 10 minutes key-down CW...
... Is that for a free-standing pole, or one that is also tied firmly to a post at the top of the 2nd section? In the second case, the optimum guying point...
... It is for a free standing pole, but I doubt the optimum guying point would change much with a pole that is tied to a post at the top of the 2nd section. 73...
Hello, Yesterday I got my 2 element phased array ready. It is made of 2 x 18m poles. my switching network is for +/- 180° and 90°. I was surprised about the...
Hi Con! Problem was on balun box. One M3 scre on coax socket is black, lower side of box around PL coax socket burned, small hole around. Inside of box, M3...
Hi Zoran, OK glad you found the problem. I am not sure why this happened. Surely the Balun is very well capable of taking the power. It must have been a bad...
Hi Holger, thanks a lot for the report. Congratulations the setup seems to be working well. Can you please let us know which type of phasing network you used...
