I live on a small lot, 80x180, in a subdivision....I have a 50ft tower with a 3L Steppir on it.....I had planned on putting another Steppir 2L about 7 ft above the tribander.....BUT......my current S
Are your interference problems "in band" or with each radio on a different band? I do not have experience with the Icom radios you are using. Do they have roofing filters? 73, Gary kk0sd I live on a
Challenges like yours demand that we not give anything away in the design of our stations. Part of that is the choice of radios, and the Elecraft K3-series rigs are greatly superior to the ICOM and Y
Just wondering if anyone uses 2 antennas on the same mast for SO2R? -- There are stations that go a step further and use the same antenna for SO2R, with a triplexer (or even quadplexer). Of course, w
Can?t really improve too much on what Steve wrote. I will reiterate that I couldn?t get a brand new IC-7300 to work here in my SO2R setup, (you can find my review on eHam) whereas 2 older IC-7410?s a
I'm one of the guys running two radios on one antenna. I'm using Yaesu radios that have roofing filters. Into a trapped vertical. It works fine. 73, Gary kk0sd Can't really improve too much on what S
I have never seen anyone put two SteppIRs on the same mast but the 7 ft separation is more than adequate for operating on two bands simultaneously. One of my homebrew 20m beams also has a commercial

Hi Jamie, Yes! For the past 22 years on my 100' Rohn 45 tower, I have used a 5L HG105CA at the top of a 14' Chrommoly mast with a 5L HG155CA 9' below it on the same mast - both turned by a HyGain T2X
Hi John, Can you tell us a little more about your SO2R setup?? How much power are you running? What BandPass filters are you using, if any?? Are you using stubs?? Many Thanks for any info!! 73, Ted
Hi Jamie, About 20 years ago, I helped build an SO2R setup at W6UE. At that time, we had mono band Yagi antennas for 10, 15, and 20 meters stacked on the same mast with ~7 to 10 feet spacing. We also
It sounds like it's the radios or grounding. I run 20 and 15 with 2 of my monobanders that are 7 ft from each other. 1.5kW. No stubs. Dunestar filters at the radios before the amps. Excellent groundi

No, it's still a dynamic range problem - wideband dynamic range (also known as "blocking") instead of the more commonly understood close spaced dynamic range. Look at Sherwood's table again and you w
Well, no, 100 kHz is intraband and the lesser blocking number is not what causes the 7300 to be incompatible out of the box with SO2R or Field Day. It's not harmonic bands, it's adjacent bands, becau
Do you mean "bonding" rather than "grounding?" An earth connection has nothing to do with crosstalk between antennas, nor to any form of RFI within a station, nor with making TX antennas work better.
