I have been messing around with tuners. I currently have a 238a and have owned a couple 238 (old style) as well. I think I am spoiled and really did not know it. The 238a has been a great tuner and I
Assuming similar quality of components, the tuner running at lower LOADED Q will have lower losses. Low loaded Q results in broad tuning whereas high loaded Q results in sharp tuning. The TT 238 is a
I have used TENTEC but now use XMatch SITE: http://n4xm.myiglou.com/ Your mileage may very but this one is awfully good. 73 David -- David H. Walker K0cop Aiken, SC __________________________________
Palstar tuners are the best tuners currently manufactured on the commercial market. The 1500cv is a T compared to your previous L's. When you compare the two on your windom, which by design stays rel
I agree. I have a Palstar 1500 balanced line tuner and it is the finest I have ever owned. I use it with a 2.2 MHz full wave loop (not a typo but that's another story)fed with 450 ohm open line. You
and I am also using a 135 foot dipole (about 25 feet high--zoning restrictions) fed with about 35 feet of ladder line to a Johnson KW Matchbox. When you say "1:1, anywhere, any band", is this with yo
Rich, Quite a number of answers I see on the board. My personal opinion is the best tuner out there is the XMatch tuner manufactured by Paul Schrader (N4XM). This is pretty well backed up by the ARRL
Set it on 40m and tune 'er up. If it doesn't tune properly, put a tapped inductor across the balanced input and find the right tap. I've had no trouble with my matchbox on 30m using a number of diffe
After more than 45 years of continual hamming on all bands and modes, I can honestly say that I never have used an antenna tuner and never found any system that will outperform a resonant antenna fed

It's roughly the same circuit as Matchbox. I used a 3906 (2 1/2" 12" long ) inductor, and a couple of the biggest caps I could find, double ganged on the output. Similar circuit and one other on Cebi
Sorry, forgot to comment on 30 meters. I tune mine on the 20 meter switch position. It was a smooth tune. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail
Even if you have a finely tuned resonant dipole, and it is actually 50 ohms at your feedpoint heighth, you're losing more db in 100 feet of coax than I am on a mismatched 4:1 swr. If you put your loa
I certainly won't disagree with you and I am also fortunate enough to not require an antenna tuner on any band but 160 (didn't get the built in antenna tuner in the Orion as I don't need it). Not all
for a quick 160 antenna look at the Gap Voyager. I got mine used for $150 and am pretty happy. I also have a AD sloper that will go on 160. the Gap has a capacitor you can order to "center " you freq

Hi Dick, I have two transmitting antennas for 160 meters at present. One is a 5/16 wavelength inverted L that is 68 ft. tall and about 98 ft. horizontal fed with a remotely tuned vacuum variable at t
Hi Roger, since you seem to proudly eschew the use of a tuner, I'd like to know what you call that matching network you have at the f/p of your inverted L--a feedpoint reactance remover maybe? I mode
That would be a good name for them, Rob. In essence, the place to use a matching network to avoid feedline losses is at the antenna feedpoint. Although using an antenna tuner at the transmitter end o
