I'm going down the rabbit hole on Baluns and Ununs and learning quit a bit. I do want to make my Final Fan Dipole with one of these incorporated. I have found so much different information on this subject. Was wondering if any one has concise info and sites that can help. I admit some of it goes over my head but I have been trying to good things as I learn about them and expand as I go.

I need to know the best mix to use for 80m through 10m. I have only come across one article that actually provides a clear set of recommendations on what to use where. It only says that 67 is ok for HF through 6 Meter. All the rest are outside the frequency range.

Thanks in advance

When I was in the Navy, one of the antennas on a aircraft carrier was a Discone, it was a HUGH antenna.
Several Transmitters used that antenna.
There were separate Antenna Tuners for each TX, and the best I can recall is the output from several Antenna Tuners all went to that antenna.

This Discone was for HF not VHF or UHF.
It had several wires strung from the top of it at an angle to the center and then slanted back towards its base.
Usually the Discone was mounted vertically except when Planes were landing when it was hinged 90 degrees and operated horizontally.
I didn't think to do a search for a webpage with a photo of the antenna to help you visualize it .
I think the Discone was 20 foot high and the center of it 3 or 4 feet in diameter.
The top and base was about 20 inches in diameter.

Not really a antenna a Ham would use, I am mostly writing about it because several HF Transmitter/Antenna Tuner were all using the same antenna for transmitting.
The Discone wasn't the only antenna used for transmitting, the Ship had many verticle antennas that were connected to Transmitters in another compartment aboard Ship.

Where I lived TV Antennas were fed with Plastic 300 Ohm twinline.
When I was in San Diego California I saw TV Antennas that used Open Wire Twinline instead of the plastic line.my area used.
Maybe it cost less to use open wire line than what I was familiar with.

There were a couple of Hams that used Open Wire feedline and a Antenna Tuner to a HF Dipole, but most Amateurs I knew used coax (me too).

Really cool story! In the end What my Elmer taught me is if I am making Dipoles and they are resonant, I don't need a 1:1 Balun and would be better off just choking out interference instead. I have been using my Fan Dipole now quite a bit and aside from needing to tune 2 ends of 10m just because of it's size it works just find without a balun. I do have a bit of interference to choke out still but I will get there.

I had a 40 Meter Dipole antenna when I was a Novice.
A neighbor Ham assembled it for me.
Fed it with RG59U .

Many years ago another Ham let me have his old ranch mounted RF Amp and Antenna Tuner. Both used Plug in Coils.
I ha en't used the Amp lately, it is 300 Watts. Can't remember what Tube is in it. I "think" 811 (not 811A).

I haven't read any Amateur Radio magazines in years, get my Ham info from BBS posts.
I will have to do a Search on DuckDuckGo to see what a Fan Antenna looks like. I am thinking two wires on each end of the Center Insulatir spread apart.

Besides the. 40M Dipole I've used a Vertical on 40 and 80, a 20M Inverted Vee and a 2M Beam.

Where this phone wrote "ranch mounted" for Me I meant RACK MOUNTED.

Sorry for the two blank posts
The icon to go to the last post is next to the Reply icon.
I got FAT FINGERITIS.

I can't help being a LID even on a BBS.
