Just this past weekend I went through all of this, exactly, but all calculations made in feet (468 / freq in mhz) with my grandson. I have the Rig Expert AA-54, which graphs. We built a dipole, deliberately made the wire a few inches longer than calculated. The dip was offset just as you showed. We recalculated from there, cut 1.5" from each side, centered the dip right around Ch. 20. SWR was 1.5 on Ch. 1, 1.2 on Ch. 20, and 1.4 on Ch. 40. But he got to see all this first hand. A great lesson! He could not transmit... he had his Dad's CB, but could not find the microphone.

Hats off !!!!!!!!! 73 de SV4RIN

Just got back into CB, radio. Thanks for help

Calum - When I started learning the Ham Hobby 3years ago I went to your KZfaq site for all things Radials. Still do. So I have a new question. Does it matter if the length of the radials are the same or different? For my goto vertical antenna I carry a collection of both 2.5m and 5m radials. Can I use them both or is it best to use only one common length? AC1NY Boston

I bought a Dx secondhand andnot used it yet but will defo be doing this upgrade....

Callum, Power to you man....Excellent update, thanks you for sharing.. You do what you need to do, i am sure that you will find most of us still here... 73's Nick ZR6NIK

Never buy anything that needs a PC to even function. In 10 years it will be an obsolete doorstop.

Love the instruction!

Very good discussion. Now we need a redo with the 8600 vs. K4D.

A Neighbour of mine had a Starduster I'm sure it had loading coil would this make much Difference?

Cal, its time for another one of your funny yet factual videos, like the Band Police or the Top Band one. Do 11 metres!! 73 G4 are.enn.em 😂

Ha, well, being only recently licensed as you know, and despite having known the phonetic alphabet for years, I struggle with mine (KK7TPM) because I always want to say "Mama" instead of "Mike" as it flows better and of course "Papa" traditionally goes with "Mama" so-to-speak. I'm working on it though. ;)

How you configure discord?

That's Numberwang!

Bro, your videos are top notch!

Greetings from Greece, my dearest friend. Do I still need radials if I setup my vertical antenna at the beach , almost inside the water ? 73 de SV4RIN

How often do you need to change/add more vas?

Riddle me this. I have a field 50+ metres long and sloping south so the top is 4m higher than the bottom. My shack is at the bottom because it has a low voltage high current solar roof for running deep well pump and i had to minimise loss in that cable. Now i run a dipole from the shack on a 8m fishing pole on 10m rg174. If i were to place the antenna at the top of the field i would gain height, but would feed it with around 50m rg11 because i have that. Will the extra height of the antenna gain more signal than the coax loses?

A DMR handheld and a hotspot will get you around the world.

Greetings from Sweden 🇸🇪 Your best comment ever. "Everything interferes with everything, It's the way it is" I will try it on my wife later.. On the plus side, if it doesn't work out i run away so its a win win for me 😂

Thank you for all of the info

Appreciate all you do, Callum! I see this as an opportunity to do a deep dive into all of the content you have provided us. 73!

You crack me up and we learn a lot also I'm a Percussionist as well! I fly Tama 9pc. Retiring soon have a buttload of radios a couple of amps.. Hope to talk soon to you be well! 333 kcx 9511.. Personal Here is Greg

this type of info is just what the hobby makes interesting Callum👌

The maritime mobile net on 20 could use some of this

I love everything about this hybrid system. Truly awesome...that's from a 40 year ham, and 1970's CB operator. lol...

I shat myself putting my dx commander

Hi Callum, the link to ebay for the side plates is broke, no seller on uk ebay? Any clue where they came from? Was it a fellow ham?

Bit of a coincidence as i made a similar antenna based on previous experience back in Kent. It was a quiet antenna , less noise. . Decided on a 4 to 1 balum wound on a ferrite Rod. 50m wire in the air. It loads on all bands via ATU. But it's resonant on 30m . Results not bad.. Still testing. Only just found your video.. everyone tells me it's a cloud burner being horizontal. It's 23 ft high. Qrm is Far better. A EFHW was a disaster for qrm at my qth. Going to make an alteration to the feed point for logistic reason as i want to install a homemade vertical antenna as well. The loop is not so hot on 10m. But 40m seems incredible. Although today station i could hear well at Hackgreen were not even audible on my setup. Also no longer can work the Sunday 60m net as all stations are weaker.. Then other stations are good. Radiation pattern is the problem. Still it's low noise. May be able to raise the height at one end.

Nope.....anxiety going thru the roof watching this 😫 Need to lay down....😢

Is this antenna better than a endfed

What about something that will annoy theat mutt like RTTY using 2725Hz and 2925Hz @60 Baud, 5 databits 1.5 stopbits.

That stupid person sounds like a dog savaging the microphone

Nice refresher Callum, 73 from the USA

Is flying a kite with a wire attached to it increase the risk of getting hit by an atmospheric discharge?

Cal, do you make these linear loaded dipoles to order? I need one for 3680 +/- for /P but being in a small flat with no outside space I can’t make one myself. Best wishes Andy / M0LSL

Im setting up mine with 28 3 meter radials. 4 on each of the 7 lugs. I did run short of wire for the last lug so Ill get 40' more at HD. I only used enough element wire for 40, 20,17,15, 12,and 10. I will order more wire from DX and use the 30m slot for an 80m inverted L. I have an 80m EFHW thats working pretty good now, My intent is to leave both antennas up and switch as conditions dictate.

Two people hold a skipping rope. One person holds the rope still, the other shakes the skipping rope left and right: the rope propagates a horizontal wave. Next, while the rope is still held at one end, the other end is swung up and down, then the rope propagates a vertical wave.

Thanks Mr. Commander :)

I can understand the reason for grounding the center on the antenna side, but if you do this to switch between radios are you not shortening the output of the radio? That could be really bad for the radio if you accidently transmit while its output is shorted?

I did 30+ years on 11m then 2021 past foundation, wow there is a big wide world out there beyound 11m wish I had done it years ago.

Hi thanks for this, great video have learnt a lot. I am a beginner and my radio starts on SW with 4.75 up to 22.0 I see some SW radio frequencies for example 3467 (random example), how would I find that frequency on my radio please? Thanks in advance.

Cal, Bigger Wrench maybe ?? 🙂

Wow been on and off CB for 45 years, and all I've ever heard is it's all about the length.of your coax, and it's never been a problem with me anyway.but just at the end of your video you said,if I got some extra wire I would coil it up anyway . which has only just clicked that you coil up the ARIEL, bottom ,middle or its on the top , so the moral of the story is it don't matter.thank you very much . DX COMMANDER.ALAN IN LUTON 💯👍

Dear Commander Collum - this is a wonderful legacy you have here. My DX Commander Classic is now up, and it is time to tune. Great idea to track the bands using a spreadsheet. My/our hope is that you are faring well, enjoying life. From S.E.Tenn., KQ4IXD
