Every so often I come across an antenna that is a little different and offers some interesting possibilities. This is just one of those antennas. It has directional properties, is very low cost. and is ideal for both small gardens and portable operation. I hope you find this Video interesting. Peter G3OJV

Peter, this was yet another great video. Thank you for taking the time to educate the "ham fam" about all the different types of antennas and how they work. That knowledge helps greatly to reduce the fear and encourage newer hams to experiment. Experimentation I believe is part of the essence of the hobby. 73 OM

i have just bought a small garden antenna what 7 band and its resonant on every band with great reports and great reviews the 7 band cobweb so for you who only have small gardens you can,t beat it. i have never had as many dx contact with my 10 watts as i do now i have had brazil alaska loads of usa and even australia twice this week 73 from M7BYF steven

Here's to ANOTHER Fifty Years, Peter! 1) I have noticed the same effect with a vertical by moving the radials all towards a general direction. It's just a slight effect, but it's a lot easier and cheaper and safer to move wires around on the ground....and there's no motor up in the air to freeze up.... 2) It sounds like this is exactly what the Buddipole vertical does with it's elevated single radial. 3) Turn the "L" up on it's side, add a coil on one of the sides, and you have MFJ's portable antenna. 4) Fold the ends out as a "regular" dipole , with a coil on one of the sides, and you have a "shorty forty". 5) (And lastly!) It seems in my understanding, that there are only TWO fundamental antennas, the dipole and the vertical. Everything else is a variation on one, the other, or both. ... 73 DE W8LV BILL

Great video. I can say this antenna works well. I had a fan version built for 40,20, and 10 with 1 radial per band at 3 meters. The antenna worked very well. On 40, the vertical section was actually an L.

This concept works. I use a pair of elevated 1/4 wave radials set at 99 degrees from each other and a 17ft whip. It's my antenna of choice for Parks on the Air. A little bit of work with a tape measure and some banana clips and band changes are a breeze. Set up and break down takes 10 minutes or less. Just fantastic.

I'm thinking of doing the same but find tape measures clumsy. I'm planning to put knots in a cord that are tagged for each band. Attaching the cord to the mount should make it even easier.

@@Inkling777 you only need to measure once with respect to the radials. Think "linked dipole". Just unplug the sections you don't need. The trial and error and measurement comes with finding and marking the appropriate whip length for each band/radial combination. The radial length remains constant at all times.

I made a similar years ago on a 12 meter Spiderbeam pole each element 10,7 meters long and fed with 450 ohm ladderline and genuine balanced tuner. Works all bands from 40 and up… worked Ducie Island with 75;watts cw on 7 MHz. And a lot of other dx… its not that directional so dont worry about the direction of the horisontal element.

Sadly FT240-43 cores are usually more expensive than mentioned. They have doubled in price over the last few years, or at least that is my impression. Something that may be worth thinking about is switching from radial to radial using a car foglamp style relay, I have used them for RF switching of antennas previously, at a low impedance point you might be surprised how much power they will handle on low HF bands...73

Using a hefty automotive relay is a GREAT idea. I agree that at low Z they work fine for several hundred watts of RF. I would add (for anyone wanting to try this) to use a choke on the DC line feeding the relay so that it does not become part of the antenna radial field. 73

@@WECB640 thank you, and yes the choke is a good idea. FWIW I have often used wall wart style power supplies from old broadband routers for the purpose, typically 12v 1a and RF quiet. We seem to find each other often in comments sections..73

For an easy to adjust radial, take a steel measuring tape and attach crocodile clip then simply pull out to required length. The advantage is it's really easy to repeat the setup. I know people will say that copper is the best and steel isn't as good, but it doesn't seem to make that much difference when we use stainless for car antennas or aluminium for Yagi's - neither is as good as copper...

I have a fan dipole in the loft for 10/12/17m. 77 countries worked this year. The 10m element had a VSWR dip, but i could never get it below 3:1. Impedance was too low. I tried off center feeding but it wasnt much help. I think it was too close a frequency to the 12m one. So yesterday i got a kitchen roll tube and made two loading coils. Took me an hour to make them and fit rgem to the 10m element with an additional 1ft of wire after the coil. Immediately resonant on 13mhz. Trimmed the wire beween the coil and original 10m dipole. It really does work. It's pretty narrow banded but i rarely operate above 14.250 so its not a problem. Can you believe that in 42 years on the air its the first time i have ever built a loading coil? Still learning new stuff. I used various online calculators as a starting point. GM4SVM

Hello Water , Thank you for sharing all this interesting technical information . I wanted to air my thoughts regarding the life of ham radio itself . Within the next few years ham radio in general will be more or less become doomed due to the falling numbers on a global scale . The ham radio hobby will somehow need to attract the younger generation , one of the ways is to this is to simplify the ham radio technicalities insofar as a further entry level exam criteria reduction & to create a user friendly system network & to advertise the hobby as in all new attractive environments with young male & female radio operators combined with affordable radios . I must admit that I'm not all together sure how the ham radio will attract a sufficient number in order to sustain all the current frequencies ?, there are commercial companies that want the ham frequencies & maintaining the ham radio revenue & interest will undoubtedly become an increasing challenge . The aim is to maintain & grow the ham radio user numbers over the next ten years or so , if this is unsuccessful thousands of ham radio jobs will be lost within the industry , if not already . Julian Robertson. Electronics engineer .

Love your low cost antennas ! Question, isn't this pretty much like the Buddistick ? I use a 17' whip and a above ground radial and have seen the directional nature of the antenna. This looks to be a much cheaper antenna than the buddistick for 20 meters and up.

In many cases the Buddistick forms a loaded vertical, but the principal is the same. Many users put the radial on the ground and that is a big mistake!

Excellent Peter,just last week I was operating from The Netherlands on 40mtrs and I put a half wave dipole along the top of the wooden garden fence both elements were ofcourse horizontal but also in an L shape because that's how the garden fence is configured and the total height above ground level is 2mtrs.I had excellent reports into the UK during the daytime and even worked into Turkey and the USA during the evening.This arrangement was almost invisible too. 73.G7HFS/PA3IKH.ps The vswr was perfect across the whole band but when it rained and the fence got wet the vswr went upto 2.5:1 so I used the internal tuner on the 7300 and all was well.👍
