HAM RADIO: The Coat hanger Antenna 2m/70cm dipole.

A really quick antenna for 2 metres and 70 centimetres, made from just 2 metal coat hangers and a small length of strip connector just add the fun.
Next time coax traps on the DX commander
I do hope you enjoy it and subscribe for more..

Great video for beginners. Very well done! I built my 1/4 w for 2m and 70cm coat hanger antennas back in 1989 for the new home we moved into. I placed them in the attic and faithfully remain in service for over 34 years. Out in my summer shack, I have 2m and 70cm dipoles made from broken AM/FM telescoping antennas. They also work great.

[@kb9qdi863]

Thanks for the video! I built one last night following your measurements mounted on a flat piece wood and it attached to 1/4 pvc on a flat base as a indoor stand. I live in a apartment with very strict rules. Took me less than a hour to build and I must say wow! I can open repeaters 30-40 miles away from the second floor completely indoors and 5-7 watts from my UV-82HP. Match stays between 1.1 - 1.3 on all bands 2m/440 on my first try. I'd much rather build my antennas than buy them so much fun! Thanks for the inspiration to build again....I'm watching your indoor stealth build now, good chance I'm building one this weekend for a fellow ham in the same living situation nearby. Anyone wanting a cheap & easy to build antenna it performs much better than the Nagoya NA-771 I was using with great reports on air. Thanks from Ohio 73's KB9QDI

[@dickelliott8927]

Great video. I built antennas like this back in 1990. Placed them in my attic 32 yrs ago. They are still up there performing quite well. I did have a flat 'V' HF antenna up for 20 yrs that ran from the front end of my home to the end of the backyard, and a tornado took it out a few years ago. But it will go back up pretty soon. My lot is 50' X 70' so I am somewhat restricted to what I can afford to put up. But the is the fun in ham radio, building stuff that works. DE W9FPJ

Hi Mike, my first 2 m vertical antenna used 3 coat hangers with vey little cutting. 2 as a ground plane / 4 leg support and 3rd as the vertical radiator. It was an improvement on the 'rubber duck' and helped me get into the local repeater. 37 years ago now! 73 G0JLF

Great video Mike. I am yet to build some antennas when I manage to get a NanoVNA. Can never get my head around how these antennas work with two different lengths of elements on the same coax connection, but hey ho. Wow look at you with the nespresso.

[@2e0txe]

Simple answer is you can have multiple elements like this design and providing they don't conflict with each on harmonics then whichever one is resonant will take priority. I'm sure we can get Greg to do a speech on it when Macc club opens again :)

I love these smaller antennas. Another youtuber was saying he made a 120 mile contact on 2 meter.😃

Great Video. Can you add additional elements to the same connector to cover additional frequencies? Maybe use solid copper wire, etc. due to the length.

How easy was that?! Will be a bit long as the antenna starts at the coax split, so that middle spacing is also part of the radiating elements when measuring up. Now to raid the wardrobe (I assume I ignore the plastic ones 😮) 🧥 👗 👕👍🏻

[@KingJarreth]

Thank you for sharing. KN6FXJ, on the other side of the pond, and I'm enjoying learning about little variants on the dipoles. It's neat to see what others are doing, and I'll be making my second antenna, using the power block idea you shared.

[@wsmith1213]

better SWR then the HT antennas I have

[@arnet3575]

The swr is good, but not necessarily the radiation. If you have a dipole for one band and then another at 3x the frequency (like 2m and 70cm) with a common feedpoint then the higher band will have a radiation pattern that is not perpendicular to the antenna and not so useful when the antenna is mounted vertically. On 70cm RF currents will flow on both dipoles because the 2m dipole is low impedance on 70cm as well. The antenna is simple to build and I'm sure it will be useful in many cases anyway.

[@mike-M0MSN]

Yep spot on Arne T and that is the whole point of the upload, to a help and to make people give it a go. :)

[@BoB4jjjjs]

How quick is that? I have only plastic coat hangers, I have a slight inkling that they won't work lol. Nice idea that Mike.

[@skaramicke]

Nice! Great project for a rainy day. My only comment is that I’m guessing it’ll be a 1/4 wave antenna with an opposite ground rather than a dipole, since the jacket of a coax is ground rather than oscillating. Kind of like a tiger tail on an HT. A balun would make it balanced, and have the element connected to the shielding also radiate, increasing the gain. Right?

[@drewby4563]

Great design Mike! I made one last night and it worked fantastically! I had to make two modifications in order to use the materials I had on hand: 1) I used 12 gauge solid copper wire 2) I used a bnc to banana connector. I soldered a short piece of 16 gauge speaker wire to the connecting points and the used the screw terminals on the banana plugs to connectthe other end. After tuning the performance was excellent! BTW - What is the name of this antenna design?? I'm looking everywhere and can't find this particular design anywhere.

[@dmcaudio808]

The name is, Coat Hanger Antena

[@aspirenlptherapies7568]

Does wire thickness matter ? I used 1.3mm wire from a hardware store as could not find metal coat hangers anywhere, I didn’t know if using 1.3mm wire mattered or not ?

[@mike-M0MSN]

No as long as the cable and wire fits.

[@militaryrig]

Interested to see what the swr would be on 70cm without the 70cm dipole legs. As a 2m dipole alone doesn't have too bad swr on 70cm.

[@mike-M0MSN]

Probably not that much different just the radiation pattern differs ( I got up to 1S point better signal on 70cm) but that could have been conditions

[@proudsnowtiger]

@@mike-M0MSN I've been a great fan of coathanger antenna on 2 and 70. One trick was to solder the inner of an RCA plug on the end of a single element for 2 or 70, and then have an SO230 adaptor on the top of a handheld - the two mated perfectly, and you had a half-wave whip that would substantially outperform a rubber helical. Used to do North London to Southampton on 10w 2M SSB on an indoor dipole and across to Holland on a 5 ele yagi made from coathanger elements basically pushed through drilled bamboo. There are plenty of ghetto recipies for construction online :) Chocblock terminals to stripped back patch leads.

[@hennero.3826]

Mike, I am a newbie and I am preparing to built something similar. Do you have any advice regarding adjusting the SWR by shortening the wires? What I mean is this: As far as I know, the 70cm and the 2m wires do not act independently, instead, they influence each other. So, is there - for example - a best practise for the order, like "first adjust he 2m part, then the 70cm part" (or vice versa)? (If that makes sense - I am not a native English speaker)

[@mike-M0MSN]

Hi, it is always good practice to adjust the longest element first as these elements will have effect on their harmonics and in this case, the 70cm element so start long.

[@hennero.3826]

@@mike-M0MSN Hi Mike, thank you. This is exactly what I needed to know.🙂

[@jimreviewsstuff]

Did you keep the (70cm) side at 20cm instead of 17cm? update: Well i built it as you did and it works brilliantly. I didn't have to snip anything off it and can access repeaters over 27miles away.
