Description: The CobWebb is a full size half wave dipole on each of the 5
amateur bands, 14, 18, 21, 24 and 28 MHz. The CobWebb is 5
separate full size dipole antennas, each bent into a square.
This makes it very small (only about 8 foot square)

Just built one,easy instructions,just make sure you have some gloves on.
Only mounted at gutter height as it is gale force winds at the moment,already worked countries that i have never before made contact with.
Can't wait to wind it up to 30FT or so once wind has dropped.
Will review again after a few weeks of use.
In my small garden it works better than my Comet H422 antenna ever has.
My view is it does what it says on the box.

Very good

Time owned: 0 to 3 months

I have only had this aerial up a few days but am already very impressed. Not only am I working DX but they are calling me.
7 new countries so far and I've not really tried that hard yet.
Mine is at 35ft in the clear and hardly shows.
Excluding a beam, this is the best HFaerial I have used in nearly 38 years of having a licence.
Thoroughly reccomended.

after recommendations for lads in my local clubs, decided to ring Steve(G3TPW)and ordered one on the tuesday,decided to collect in person on the saturday... after being shown the mini manufacturing empire and vast antenna's on various tests in and about his garden...Decided to biuld in the following day.. easy to follow instructions,and within the following couple of days..qso were rolling in from everywhere>>> first VK, on 100watts with a 5/9 report...think thats a result...there are imitation around.BUT will they be as sturdy

Being very limited for space at this QTH, even getting a dipole out for 20m is impossible.
A postage stamp sized back garden meant it was vertical or something like the Cobwebb.
Given the fact that I would be pushed to get any radials out, a vertical was a no go.
Mounted @ 30ft on T&K brackets on the side of the house, first call on 17m got me in to Cuba.
Since then, have gone to work all over the world on my paltry 10w QRP.
Given the fact that conditions are far from good at this time and that I am using low power,
I was more than happy with the results this rotary clothes line has given me.
Make no bones about it, it's not a miracle antenna and theres no voodoo involved,
but for someone with limited space, this is the perfect way to get 5 dipoles out in a small 8ft footprint.
I would imagine something like a CB vertical may outperform it on 10m but no way for the other bands.
Though it does work very well on 10m as my logbook shows!
Ideally, mine would be mounted a little bit higher, but unfortunatly thats not possible here.
Doesnt seem to suffer too much being lower though! I've worked more DX lately than I've ever done with tuned up CB verticals and compromised doglegged, bent di-poles. A beam its not, but cleverly designed it certainly is.
Instructions are very easy to follow and take you through assembly step by step.
Yes, you can build one of these yourself for a lot lot less,
but I doubt that it would last as long.
Fishing poles are very thin walled. The Glassfibre tubes used on this are almost 5mm thick.
If like me, you are pushed for time and dont have the materials readily available,
put your hand in your pocket and treat yourself.
For a high Q antenna it is surprisingly broadband.
The only time the ATU comes into play is for the lower digimode portions of 20m, or wider spectrum bands.
As a rule, the tuner doesnt come into play. As someone else pointed out, take time to get it to resonance.
It might take a while to tweek it here and there but it will pay dividends once its in the sky.
If you're relying on your ATU, you're defeating the object of using resonant di-poles.
Mine is tuned to the centre of the voice portions of each band and works brilliantly.
No nulls. Ability to mount my co-linear above. Rugged. Low profile. Efficient.
Would I buy another? Without a doubt.
Cheers.

I have this at ridge height and it slaughters my end fed wire 68 foot long up at 40 feet above ground , which has lots of ground wires ,,,,, 3 to 5 s points difference , i didnt believe the hype of this aerial until i tried it , its not a beam but its a very useful tool , Try one ,today

It works great...

Say what you like about wires and beams but for those of us with out real estate and fussy neighbours...this is a great solution. Mine was delivered well packaged and went together in slow time (my choice) without a hitch. All 5 bands were fine. I only found 20m to be slightly off but the ATU brought it in well and working areas of the world that were previously never heard cant be bad eh? I have since move to another non-ham friendly residence, bought an analyzer to fine adjust the lengths as required and am looking forward to getting the webb up with the Flex.
So, in response to the 'dont believe the hype' comment....of course directional metal is likely to be better....but compromise is a word you have forgot.

I have two of these of different manuafcture date. Both seeem to be wearing well. Excellent performer all round and, in better sunspot conditions, will really do as well as any dipole (unless the diploe is way up high on a tower). If you compare the CobWebb to any ordinary, relatively low wire antenna, at around 20-30 feet (7- 10 meters)then the 'Cobby' will perform as well or better. Also, remember it is omni directional. Another plus, all the bands have their own diploe so, no ATU is required, therefore losses (no traps). Web Site say all you need to know and is a very interesting read.

No miracle but extremely good

Compact, horizontal omni, looks better up in the sky than down on the ground... and works a bit better up there as well ;-) Being a horizontal, free's up the mast for a vertical atop.
Easily constructed with concise instructions but watch the fibreglass and make sure it's resonant where you intend to be most active on a band.
In use, during absolute sunspot minima (I hope it is!!), it has exceeded my expectations and allowed me to work several continents on low power in a short time. I never believed this was a miracle antenna and it's not, but it is a very good solid performer on the bands and I have been shocked at my callsign coming back to me on some pretty big pile-ups.
When the bands open up a bit more, everything bodes well for decent worldwide communication with this antenna
Tunes up easily on 6m, although not exactly efficient there. A dedicated 6m section should/could be a possibility for a future design?
Ordering is 'quaint' for this day and age. Cheque sent off, antenna arrived a week later, which is fine.

well a review of my review...having experimented with various antennas in my limited english qth garden...20x18feet wide...the cobwebb for the higher bands ie..20 thru to 10mtrs is absolutely outstanding...my cobwebb is 27 feet above ground and whilst not being at the optimum height of 33 feet for 20mtrs it is perfect for 17mtrs ...gonna hit that band with a vengence when the sunspot maximus opens hi!!!all in all the cobwebb has been up in the air thru gales/snow/ice/rain/,not a problem..if its good enough for my buddies in the falklands at 100mph gales its good enough for me...if u r gonna buy a g3tpw cobwebb..please please please take the time to get it to resonance..would i buy another one if mine got busted beyond repair...CERTAINLY I WOULD!!...wish i could rate it more than 5 outta 5...more like 10 outta 5!!!...my cobwebb antenna is worth while being a ham...20 thru 10 i can work...80 and 30 mtrs via home brew end fed sloper and home brew 4 to 1 balun....if u wanna work 30/40/80/ and top band steve webb is also working on that as well!!!via the cobwebb...regards de 2e0jkd ..

having owned my cobwebb now well over 12 months since i wrote my last review i am more than happy with it....if i can hear the dx station he can hear me...small enough in the air at only 8.5 feet wide/fully omni directional/no rfi or tvi emc issues..i was going to swap /buy a hybrid quad or ma 5 b mini beam but why bother when the cobwebb is fully resonant where i want them to be on 20/17/15/12/10m all at 1.1 .3 no atu 27 feet agl with 50watts....i prefer CW and when i call in i,m always heard even at 5watts qrp to new york one sunny saturday afternoon....for operators with small gardens or no gardens even. this baby really does work and i only wish steve webb would design an add on for this cobwebb so it would cover 40/80 meters also!!weekend od 17/18 march really high winds here n/e england gusting to 70mph cobwebb shrugged the wind off when fences are being knocked down ..no damage to the cobwebb and its been in the air well over 12 months now...see pic on qrz.com....well impressed still? UNDERSTATEMENT!!.. buy one and see for yourself..i am well hooked with it even tho i came close to p/ex it for more expensive verticals or mini beams and hybrid quads...it is a good pieco o kit...tu es gl ee
