Hi all.
I installed a rooftop FM antenna and am starting to regularly record live FM music broadcasts received on a Marantz 112 tuner. I get a strong signal, but I'm also getting some sibilance ("essing") and occasional faint soft buzz-saw noise. I'm looking for advice on how I can approach...
Edit: I didn't catch the autocorrect "multiparty" in the thread title until too late. It's supposed to be "multipath."
Hello everyone,
A little background: I live in a suburban area of Chattanooga, TN in the USA. Chattanooga is in a valley surrounded by mountains and ridges. I don't live in...
I just purchased this unit and know little to nothing about it. I’ve tested various functions (am, fm, tape, phonograph, speakers, power inputs), all of which work well. I did a simple google search to find out a little more like when it was made, what kind of unit it is (solid state etc) and...
Being fed up with the crap performance of my 3 element yagi indoor FM antenna I calculated a log periodic dipole antenna (LPDA) for 86-110 MHz. The resulting array is 2 m long and has six elements (attached). The results from MMANA-GAL are pretty impressive:
Don't you just love 3D...
Hi,
Although there is ton of information on Great antenna's, the truth is that lots of First time Vintage-Audio lovers and Enthausiasts, are a bit overwhelmed by al the valueble information.
They need a simpel DIY solution witch can be made from some scrap materials and some handy work.
Now...
I’d like to improve the quality of my FM antenna and am struggling to research exactly what I need.
I have a Sony STR-DH770 receiver. The manual calls the antenna type an “aerial” antenna (single wire).
It gets decent reception, but never for all the stations at once. I have to move it around...
I set up my Onkyo TX-8020 earlier today. I was not able to connect the FM antenna that came in the box with the unit, however. The antenna uses a connection I am unfamiliar with. It appears to be similar to a coaxial cable such as the kind found on a TV antenna or a internet modem. I used a...
I have 25' of 3/8" copper tubing and bad reception. Have had the tubing for several years, it's doing nothing, and I have no other plans for it, and after reading about the outdoor use of vertically mounted dipoles as pretty decent omnis, it occurred to me that I have three hall closets in a...
I know there are several threads about FM antennas, I have a few things to clarify.
1) I plan to use some heavy-gauge copper wire for an element. how long? 38"?
2) do I split it in half and attach one lead wire to each piece?
3) if I keep the element in one piece, how do I attach the lead...
I live in a densely populated area (flat terrain)and am interested in building an antenna specifically for FM radio. The copper j pole design seems to be easy enough to build. If tuned to 98 MHz, what range could I expect?
My goal is to
A) increase the FM signal
B) listen to a station ~40miles...
