This is my Flowerpot or coaxial dipole antenna for the VHF aircraft band. These aerials are very easy to make, as you'll see from my construction details.

Holy crap it works! I made this flowerpot antenna and I'm picking up things I've never been able to pull in before! Previously with the whip antenna I'd bought, I would get nearby airborne planes. Now, with the flowerpot on the ground, I'm picking up the tower, planes on the ground and ATIS 6 miles away. There's some noise but it's not overbearing. Tomorrow I hoist it up into an oak tree. Hoping for even clearer signals. Woohoooo! Thank you Ray!

It is very simple antanna I already make few, one is for 2meter FM operation , another one for APRS and work. Very simple. Coaxial bazuka dipole isnt easy. This antena origin from 1930 es. Originall name is T2LT , I have no HOA restriction but have problematic neighbours. So I try to hide antenna without compromis rf capability.

I have fixed it to a fence post and the top of the antenna is about 10 feet up and working a treat, I have Shorham by sea Airport about 6 miles down the road and the tower is booming in like never before. It is on 129.150 mhz I can also hear Hurn West Swanwick on 129.425 and Hurn Swanwick on 135.050. I am using the Grecom PSR-282 handheld scanner. Many thanks. Paul

Hello Ray, I am absolutely staggered as to how good this antenna is! I have been using the D 777 antenna which is mounted on the roof of the house as high I dare climb up the ladder and connected to my Uniden UBC 125XLT Airband receiver. The setup I find to be excellent. However, this flowerpot coaxial dipole antenna that I made following your instructions isn’t even on the roof of the house, yet I am getting perfect reception and full signal strength. I don’t quite understand what’s going on here! I’m going to spend more time performing tests and hopefully going to roof mount it soon. Thanks very much for producing this video and I’m blown away as to how good this Flowerpot coaxial dipole antenna is. It took 30 mins to make and is my first antenna. I'm planning to make another one over the weekend, using a small diameter tube.

I am going to make one of these right now for airband. Since I am going to plug it into a RTL-SDR (which is really more of a TV tuner as originally created) I am going to try building it with RG-59 style cable TV coax of which I have a ton laying around. Since it is receiving only, I have heard that the 75 ohm nature of this cable really doesn't bother the RTL-SDR. What I can't see yet is whether the calculator (see description link) cares what kind of cable is used (RG-58 versus RG-59). And yes, like the French talking about love, you UK types could read the phone book and it would sound charming and educated. Had the pleasure of playing a carillon concert at the War Memorial Tower at Loughborough a decade ago and enjoyed the hospitalityof the British people. Enjoyed the video. Subscribed!

Mounted up only 10' on the side of a building and working fine, receives aircraft 30+ miles away at high altitude. Painted the 3/4 PCV it is inside the color black, and with the black electrical tape securing the coil, I must say it looks, as you say, smashing. Thank you again for your excellent video. PS. The calculator website did reference different coax types and what their degree of loss would be for the calculator's input. Didn't see that first pass thru.

Great vid thanks Ray. Regarding the coaxial coil winding you called a choke but I believe it might form the impedance matching network. Given the theoretical impedance of a half wave dipole is 73 + j 42.5 (~75 ohms) and the coaxial impedance is 50 ohms, an impedance matching network is required. In this case a 1/4 wave coaxial Q section implemented via the coil. Tweaking the coil turns will tweak the matching impedance for minimum VSWR (return loss) as you mentioned.

Hi Ray, I’ve been using the Flowerpot Antenna for almost a year now with excellent results. It’s externally mounted using the same conduit as in your video and when checking it recently I found it to be full of water despite having end caps top and bottom! Not really sure how the water is getting in but we have had some intensive rains storms of late. The conduit does work well but I’m sourcing “Fibreglass” tubing that’s thinner than the conduit which will improve in terms of less wind resistance and planning to increase the height of the antenna by I hope another 3m By the way I also made another Flowerpot Antenna this time using RG213 Coax, I found it no better that the RG58 Mil spec that I use, so staying with RG58.

I’m sorry to ask, is there any limitation of the cable length that will go to the radio? Because i saw one video about dipole antenna, it is best at maximum of 15 meters. Sorry to ask you about this.

I made one of these this afternoon. I used a five foot length of white pvc pipe, 21mm diameter and a scrap piece of UR43 coaxial cable of about 9 foot in length. Screw-on BNC connector for a quick finish and test. It's remarkable how well such a simple aerial works. I connected it to my Uniden UBC370XLT scanner and I could clearly receive the Pole Hill VOR from approximately 30 miles away. Full squelch setting and with the aerial just leaning in a corner. I expect it will perform even better in the loft or outside. BTW, I used a nylon cable tie to secure the coax to the pipe where it comes away from the coil. Stops it unravelling the electrical tape (I've also run out of suitable heat shrink sleeve).

@@g4nsj Ray, if I want to fit an RF connector (probably a BNC) what is the longest amount of coax I could have between the connector and the choke coil ? If I fitted the bottom end of the conduit into a two way box, I could fit the BNC to the box lid and have 3 or 4 inches of coax in between. What do you think ? Thankyou.

I thought I would add some details on air band frequencies, the total civil VHF air band is 108mHz to 136mHz in most parts of the world, in some parts it extends to 137mHz. Air band coms occupies from 118mHz to the top of the band and are vertically polarised, the frequencies below 118mHz down to 108mHz is used for navigation systems such as VOR and ILS and are horizontally polarised so receiving them with a vertical isn’t going to work very well. If designing for coms I would calculate for 118 to 136mHz.

You are right yet again Ray the discone is terrible and going back tomorrow. Very weak all round specially air band. I swear by your flower pot design it is truly amazing and beats the discone hands down on HF/VHF and UHF (DAB, DAB+). I might try out a Moonraker Sky Scan. At least I can take that anywhere if needed and they are good indoors as well according to the reviews but that remains to be seen. Good luck and keep safe Ray and once again thank you for your input.

Hello Martin, I made a similar purchase of a wideband Discone antenna and like you found Airband reception poor. But of course having an antenna coving such a wide bandwidth I would suggest doesn’t excel at any one frequency, hence an antenna specifically designed for a particular frequency provides the best reception. The Flowerpot Antenna as shown in Ray’s video which I have made to Ray’s exact specification provides “outstanding” performance. I have the Flowerpot Antenna externally mounted which is picking up frequencies that I haven’t heard before. There is something very special about the Flowerpot Antenna its easy to make, reception and the distances it can reach is excellent. It’s also very discreet when externally mounted and withstood storm Eunice with ease. You said “the discone is terrible and going back tomorrow” did you manage to get your money back?
