Make a discone antenna for my SDR radio

- In this one i experiment with making a diy discone antenna. It is probably not a great one, althougth its performances are better than my old groundplane. Many parts are temporary parts : pla isolators... and it is clearly not waterproof... but as a proof of concept, i consider it a success !

This is the very project I will be doing myself for Airband, 108-136 mhz. I have a commercial wideband Discone but only need elements of 590mm for airband. I just want to build one because I am a model engineer and it is a project for the lathe and drilling/tapping. Where you have used PLA I will use perspex/acrylic discs. Nice work.
I'm just getting into radio, I live in the UK and have just brought my first rtl sdr. Would a discone be a good antenna to start with or are the telescopic ones okay ?
How to determine the number of elements needed for that?? the other designs has 8 legs, why 6????
Nice video. A question for installers out there as this is a place who has experience. I have a discone antenna which is being installed apart from metering the cable end to end for continuity inner and outa. Once connected via N type aerial end and bare on the other before going up on the wall if I meter with a multimeter the inner core should it beep out on any part of the antenna and same with the outa cable? I take it it's not a loop in anyway? Should it beep on inner core to the whole antenna? Just thinking test wise before it goes up as have to pay to take it down again if it's wrong.
I have a tranceiver with 80-60-50-40-20 meters, would it work for those bands?
Nice work, not economical but challenge is here: congrats !
Yes, may be a bit more expensive than a commercial one :) But where is the fun ! Thanks !
I was about to switch off when I saw the lathe. Then I said I'd continue because I'd never really seen metal work before.
What if you don’t have a lathe
Yes... this was mainly an excuse to play with the lathe ;)
Antenna D-130
Can you make an discone antenna to receive TV signals ?? Since the antenna can receive signals can this be fine tuned to work with transmitted signals in the UHF band between 470 and 608 MHz frequency range.Would be interesting to see if that would be possible. Nice video fella for sure.
Yes you can make a discone for any VHF/UHF frequency. But this antenna has no gain and for tv application you would probably look for a more directionnal antenna like a yagi.
@@tinybricole7774 Thanks for giving me direction TinyBricole. One learns so much when others give direction to questioned asked.
@@victoryfirst2878 Totally agree with that. Thanks for your comments !
@@tinybricole7774 I am wondering if you would have some insight into antennas. From looking at TV antennas, two stand out. Channel Master 4221 whisker vintage antenna and the Grey-hoverman double diamond antenna. These items were made years ago and to this day have been improved upon, still used to this day. What puzzles me since technology has moved on so much is why antennas have not really moved in the same direction ?? Peace
@@victoryfirst2878 Thanks, i don't know a lot about tv reception. I'm more into radio stuff these days : just got my ham license ;)
Step 1. Own an assortment of expensive-ish tools.
Step 2 (optional?). Know how to use them.
Step 3. Painstaikingly build discone antenna (having gotten several steps wrong, possibly several times, during the process)
Step 4. Casually browse the interwebs, nursing your bruised and bandaged fingers, to discover that you an order a fully-functional one online for a very moderate amount of €/£/$...
Lols got all excited till the lathe popped up
1:22 you should not go back over the metal with the chisel on the last cut if you do that it will look less good
OK, thanks for the tip ! I'll try that !
@@tinybricole7774 1:47 also for this you should lift the chisel from the metal then move it back and the put it back on the metal if you keep the chisel on the project when turning ik back it can get stripes on it
