Attaching Coax to a Dipole (

[@woodskid4ever]

Dave, I enjoy watching your videos. You look very much like my dad, who left Earth this past September 10th. I’ve been a HAM since 1989, and had many gaps in my knowledge of all things amateur radio until finding your channel. Thank you for sharing your knowledge!

[@CraniumSlows]

Thank you so much. I'm newly licensed and had the same exact question! Appreciate your years of videos, they're fantastic.

[@Sydneywizard]

Brilliant! Just passed my Foundation license and looking to build my first antenna and this video answered a bunch of questions for me. Cheers from Australia.

[@ReedAB8AS]

Thanks Dave de AB8AS. You are a true Elmer to all new amateurs. 🙂

[@johnsinclair3067]

And for older ones, too

[@dsandrews3]

Thanks!

[@TH-fg1rp]

Thank you! Exactly what I was looking for.

[@redneckways1933]

Thank you, that helped me a lot. I have been trying to get something to work with parts I have laying around, and I believe I can make this without spending a dime.

[@Littlelewie151]

Thank you for being such a great mentor!!!

[@ryanv7075]

Thanks Dave! I have been having the same question for random wire antennas. People usually leave out the final connection details. There is also varying information on whether you need a balun, counterpoise, or ground connection. Not sure of if the answer can be different for receive only antennas, vs those that will be transmitted on. I appreciate all your help!

[@W0KNI]

What ever wire layout your using, random, EFHW, OCFD - it's all about the ohms on the wire when considering what balun/unun to use. Random lengths (not really random) perform best w/ a 9:1. EFHW best perform with either a 49:1 or 64:1. OCFD and Horz. loops work great with a 4:1. I've made them all and all of them will get you rewarding QSOs. Have fun!

[@ginahammer6966]

Thanks for making the video.

[@woutb.5210]

Hi dave, very good info with this video. On 6.00 you show a 9 turn loop. What is the diameter of that loop? Thank you for answering.

[@DomBru]

what is the diameter of the 9 loops for the balun ? thanKs

[@donaldsmith3048]

All the balun I have wires coming out. The rings on the sides are just for stran and the antenna wires are connected to the wires coming out. This makes it easy to solder the antenna wires to the wires coming out

[@KN4YEM]

THAXU David your a truely a helpful OP

[@inspector1794]

Good explanation. You might add how to secure the coax to the center insulator as a strain relief to take the coax load off of the connection.

[@hobbiesthings6948]

Dave, I was thinking of getting ready for a radio room, but, was not sure how to run the coax into the small 10x10 addition. I have seen a few mounts that fit in the window and seen 6, 8, 10-inch bulkhead connectors, I am thinking 6+ antennas. I live in a cold snowy winter area so the window plant is out, I was thinking of the bulkheads but that will leave them exposed to the cold, wet winters. As I searched KZbin and antennas boxes seeing if there was such a thing and found a few videos on buzzsah, he is using an outdoors electric box and installed 15, 2-inch bulkheads in the panel and when it is done or needs to work on, add to, or remove, he just opens to door, meanwhile everything is protected from the weather. What do you think?

[@dmullenaux]

I'd love to know his answer to this too. I have a slump block house and I need to get through an exterior wall as well. An electric box is what I'm leaning towards, but I'm more worried about drilling a hole in my wall and what I might find in between.

[@patriot9455]

This a newbie to HF question, based on the idea we are going to buy some acreage, with enough room to put up a nice HF dipole. If I want to work 160 meters, would it help to use 4 times the loops as you would suggest for a 40 meter unit. I am also looking at a "sloper all band" antenna, with a length equal to the lowest frequency band I am looking at using. I may have room to plant a 160 meter 1/2 wave sloper. I have not measured the available space. Would that make it where I would not need a lot of power to reach as far as half way around the world.

[@W0KNI]

If you have the trees available on your new property, a full wave 160m horizontal loop (square layout as possible) works great for both TX/RX. Pretty low noise and you only need to have the wire mount points about 20-30 ft off the ground. Use insulated wire.

[@patriot9455]

@@W0KNI Thank you K0XHF

[@NimeshYadav-s3k]

I wanted to ask a question... I am facing network issues inside my house so, can I use a yagi antenna for outdoors to receive the signal from the base station and omni antenna inside the room without using a repeater to boost my signal strength?

[@billlamb8944]

Thanks David. The man with the answers . Bill KD9HWH said that. 73

[@masterscarpet]

Any problem with feeding a 2m dipole made from speaker wire by having a section of coax from transceiver connected to a 15’ length of speaker wire split on the end to make the dipole?

[@ronlewis6394]

What if I supply the the dipole with ladder line for a verticle rise and have a SO-239 connector at the base. How does this effect the dipole or tunning?

[@greglawrencemusic]

For the mere price of $40 you can buy a nanoVNA and find out!

[@forgetyourlife]

@@greglawrencemusic so in other words, you don’t know either.

[@forgetyourlife]

Ron, that sounds like a doublet which will work but you’ll need a wide tuner.

[@greglawrencemusic]

@@forgetyourlife So in other words your an ass that has no idea of what I do or do not know. lol.

[@duartebettencourt349]

Hello! I have a simple question about a ocfd 4:1 and 1:1 choke, the coax has been tested fine positive to positive and shield to shield, but when connected to the dipole it is shorted from shield to positive. Is this normal? Thank you in advance Duarte Bettencourt Kb1mlq

[@gotman4409]

Unfortunately some folks will settle for using the plumber solider but I don't understand how they get that to work. In my experience , the joints break down electrically and then what you end up with is a solid made antenna that doesn't work. It especially doesn't work with antennas made from copper pipe. I ended up with an expensive mess as copper connectors can get expensive.

[@TheChristoqher]

I am making a yagi antennae for my router where do i connect my coax to the antennae

[@Wink_Dinkerson]

I'm only going to be receiving so no need for a balun ....correct ?

[@timbacchus]

I love the budwig connecter

@Dave Casler - Sir, the dark spot on the back of your left hand, if you have not had a doctor look at it, Please do. It looks much like the skin cancer I had on my arm. Great video.

What is a diode antenna?(2:34) lol jk;) Love your videos Dave:)

[@daniell8387]

Best practices for hams: If you can afford to lose it and want to try, and won't get hurt: do it. We're experimenters, if baluns have made things worse in your experience don't use 'em, and if you do use them and they do help you then go to town.

[@timdbl7804]

Using decent balun with a dipole should be straightforward. Without a balun, there will likely be radiation on TX, and pick up on RX, by the outer of the co-ax. And probably less current in one leg of the dipole. Usually, these are undesirable.... unless you deliberately want the co-ax feeder to become part of your antenna element!

[@daniell8387]

@@timdbl7804 right but everyone and their uncle had an opinion on the myriad aspects to our hobby, and baluns can be easily and safely implemented in most cases as well as cheaply if you make them. Give it a shot and watch the swr meter

@@daniell8387 Hi Daniel, I should have put my initial comment at the top of these comments, as it was a comment in response to OGY's mention of failures with baluns; wasn’t trying to rain on your comment 🙂 Yes, I'm all for hams experimenting; it's how we discover better ways of doing things.... 🙂
