Yuri, The parasitic array as we both understand are not meant for ultimate F/B. I like them only on the low bands where one can listen on a Pennant, or Beverage system. The other thing you might look
TTers, I am searching for a source of real ladder line, 500 feet if possible. I do not want the window type line. If you know of a good source of new line, or are a dealer for this please do contact
I sent a message directly to Micheal the originator of this thread but I see from many comments that one solution that always works was left out. I have tried to do the ingore the SWR approach of Ste
A bunch of stuff snipped out: "2) I have to choose whether to use full size 40 meter elements, or to load them somehow (probably capacity hats at the ends of the elements. 4 2' spokes shortens the el
I have just learned that Bill Orr, W6SAI has become a SK. We have lost another icon of antennas. -- Jay Terleski WX0B - Array Solutions Phased Arrays - Horizontal and Vertical RF Switches, Antennas,
Al, The stacking distance for this antenna will depend on the active section of the boom for each band. Assuming the 20m section is the longest lets go from there. Figure the boom length in Wavelengt
Interesting, seems like here in Texas the propagation changes more dramatically during the day to favor different combinations of beams. I frequently find that the lower or middle beam combinations w

Thanks to all who answered the survey. I won't go into details with everyones summary but there seems to be a differing opinion with the Stack Crowd on the all combinations Vs just keeping all antenn
Dear friends on TowerTalk, The WX0B StackMatch is now being manufactured and sold myself at Array Solutions. Please visit my new "underconstruction" Web-site at www.arraysolutions.com to get the late
Tower men, I have not been on this reflector for quite some time due to my work load as Array Solutions continues to grow. I had to cut down on the emails and unfortunately this list (one of my favor
Dear TTalk Readers, I have been told by a number of friends that the TTalk reflector was once again active with Prosistel/ Alfaspid bashing. As many of you know I am the importer of Prosistel from It
I'd be even more interested in the details of the "Navy approval"... Thanks for the request, I have posted the brochure for the antenna/positioner system, which includes the mil-specs it meets for sh
Questions: Now that Rohn has been acquired and has been running under the new parent for a while, has quality improved? What's the opinion out there on the Nello products, specifically 55N? My one ex
Shamless plug Mike, and Tower Talkers. Array Solutions Un-Uns are available. 22 ohm to 50 ohm Un-Uns are made here all the time and we call the Mini-StackMatches. They will handle 5 kW CW. We can cus
Gents, The K9AY new loop is still Gary's great antenna design. It does require a ground but not 1/4 WL radials only some that are say 16 feet long if you need them at all with the required ground rod
The best way to answer these questions is to get a copy of HFTA, which comes with the ARRL Antenna book. It lets you model the pattern of stacked antennas, varying spacing, etc., and factoring in you
Currently Force 12 and SteppIR are the only manufacturers that use our protocol to produce useful comparable performance figures. If Optibeam figures were produced similarly, then I'd be more incline
Clay, The relays we use are specially made for us; they have our part number on them. You have to buy them in qty of 500+ at a time. But I do sell them They are not $45 but $16.00 each. They are USA
