Yes, I will agree that running 1 KW, a full up purposeful high power tuner, and balanced as needed is best. Most of us use 100 watts or less. Stuart Rohre K5KVH ______________________________________
I agree with the general proposition it is better to adjust/tune at the feed point, but I also believe one might clean up a relatively small mismatch using the internal tuner. For example, I have a n
MFJ has a new remote auto tuner that costs about $750 - supposed to handle 1500 watts. They have one that handles 600 watts for $400. Some of use with 43 foot monopole vertical antennas are waiting t
Good question, Frank ! My answer is... "Several." I did this, myself. I built monoband dipoles from aluminum tubing. Costs is about $60 - $130 depending on size. Solid as sears and only require a sin
As... yes... Although, I thought Frank was suggesting it is better if you could put your tuner / transmatch outside at the feed point, and (more or less) take the coax out of the equation. N'est ce p
Actually with just 2.5:1, your OM VII does not require a tuner. Just pump the power into the coax and forget it. The rig can take it. That's how Ten-Tecs are built. With your TS-590 you probably need
What James, a Chinese product with quality issues? Are you serious? ;-) Now I'll be serious and say that the CG-2000 which is the low power version MFJ is re-badging, in the meantime is shipping at a
You do not get the coax out of the equation unless you manage to get the impedance to exactly 50 Ohms, non-reactive. All of these auto tuners come close but almost never get it to 1:1 non reactive. T
Geeze... Rodney... I think I could just about sell my wife to have an antenna like that. ;-) _________________________ Anonymous - K8JHR _____________________ 4 to 1 balun and I can tune 160 to 10 1t
I must admit to not understanding what MFJ means by input power versus output power. I figure output power is what comes out of the amp on the way to the antenna, with the tuner in between... OK... b
This is the AT-AUTO. I have one. But you cannot locate it at the base of the big stick outside. Palstar's new auto tuner can be located and operated remotely. It will cost over $1500 US. Ouch. I have
BACK in the pre-historic times, when there were no transistors and only tubes, the US had a power limit of 1000w Input Power. P=Isq. R, or P=E/I were common formulas to use. Let's take the second one
That sort of specmanship is troubling. Depending on what is 'too high' with regards to SWR. Most folk don't need a matchbox unless their SWR IS too high. A matchbox that cannot handle 'high' SWR is a
Frank, I did begin with "back in the pre-historic days". What you are calling a deceptive spec was actually the law. It is how the FCC defined our maximum power. It is how everybody measured back the
Rick and all, I had an 80-meter dipole with balanced feedline at my old NJ QTH. I fed it with a Heathkit 2060A tuner and got good matches on all bands 80-10. No need to cut feedlines. The 2060A was r

Hi, Rick Has anyone converted the Johnson KW Matchbox to an 'Alfred Annecke' style matchbox? I have a KW Matchbox and you are absolutely right. Works great on 80 and 40 feeding a 80 meter dipole with
Dave and everyone else interested in the Annecke tuners, let's take this OFF of the Ten-Tec reflector please. I don't want to get my fingers slapped by the moderator. I will answer you direct. 73 Ric
Hmmm...I must be one of the lucky ones. I have a 130-140 foot long dipole, 25 feet off the ground, fed with ladder (window) line. I am using a stock Johnson KW Matchbox. I can get a perfect match on
Carter, you are indeed lucky. The funny situation you mention is the same that happened to me when using a T-Box with external balun. The SWR did not look that bad at all but the Omni VI+ kept blowin
To return this to the original subject I started with After all the discussion, I decided to switch my tuner to bypass and see where I was and what happened while I was on a local 10M net. The answer
