John KK9A Looking forward to getting back on the Top-Band for the next couple of months and working some contests and some good DX. I'd appreciate your recommendations on the antenna options for my
As I recall, ZF1EJ's station uses a log periodic, a tribander and possibly other antennas and he is on the southern side of the island. Log periodic antennas typically do not have much gain if they w
Gary, It will be great to see some of your other products again. I have owned a RAS-8x2 for a number of years. It makes switching Beverage antennas so easy plus it has a preamp. I put mine to good us

The ARRL DX CW contest is a DX contest. I would not chose this event to work someone in my own country, it is unlikely that the QSO will be logged. John KK9A Hello Jim etal This has probably been men
With a remote receiver it is easy to listen on the band while you are transmitting. It is much more difficult to run SO2R on a single band when the transmit and receive antennas are on the same prope
It must depend on your QTH. When I moved to North Carolina and put up a tower I ran the rotator cables and coax on the ground to the tower about 250' away to operate the Sweepstakes contest. This was
I am not sure what supplies that you have available in the Republic of Congo. A Pennant should fit in your operating area. It is pretty easy to build and it is not ground dependent. John KK9A Dear fr
It has been a long while since I have operated a 160m contest. I remember some very slow hours and having a way to tune a second radio to look for new stations and multipliers would have been great.
Brilliant! I like this idea. John KK9A I agree with John's (KK9A) commentary but not necessarily that it needs a new category. Just add it to the assisted category. Leave the unassisted category as i
I did not recall seeing tests for verticals a wavelength or more way from the sea so I checked the team vertical website and found the following: John KK9A While field testing the verticals this past
I have several Array Solution StackMatches that came with rotatory switches. I found the rotatory switches to be very awkward for changing stack configurations and I quickly replaced them with MicroH
Doing this will put the weakest signal (-2.5 dB) at 350 degrees instead of 0. John KK9A Hello Jorge, The common 4sq orientation in the eastern U.S. is 45/135/225/315 degrees. That simply is to put th
I think that you are lucky that it lasted two years! I set up a temporary tower/rotator when I moved to this QTH and in less than a week the rotator and control cables were chewed so bad that it did
Your tower is probably close to resonant on 160m. When I have modeled a wire vertical near my 150' tower, the tower acted as a reflector. You may be able to get a little gain in a desired direction i
The antenna you describe is 1/4 sloper. The tower radiates and the effectiveness is very dependent on the tower, guy cables, mast and beam on tip. You have to model your installation to see if it a g
To score well in a contest you need to make efficient use of your time. You have no 160m antenna and for reasons not mentioned no way to install one. Using a non resonant antenna may cause damage to
This is easy to model an inverted V to see the actual pattern. I am sure that whatever configuration / direction you use will be inferior to a top loaded vertical. BTW two weeks ago I used a 300' hig
Perhaps you are looking at the N connector lead, the actual pin where RF flows is Ø.120 which is not much smaller than a UHF connector (Ø.156). I use a number of N connectors at my station and have n
