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)

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

Time owned: 0 to 3 months

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

I have owned onw for over 10 years and used mine both in a loft and outside. I run QRP (8W pep), and have worked lots of Dx on all bands 28 - 14 Mhz. Its not a beam, its ommi-directional which can be on the down side but can be a advantage. Any breakage of the spreaders can be rectified by return from Steve, who can answer any questions on the phone. Yes it does what it says, Yes it can help you work DX, (Ive now got QRP DXCC), For those with small gardens, no gardens, consider this, it works, (better than my windom) Weak points? none as longer as you understand its not a beam!! Yes i would consider another later.

works better than better
|
Time owned: 0 to 3 months

i have a really small back garden..24 feet long 18 feet wide..tried various wires /small beams etc but no space at all..recently purchased the cobwebb antenna and used an mfj 209 antenna analyzer to fully resonate the antenna..its up at 30feet max and the stations i can now hear are unbelievable..america 59 on 20m/brazil and worked him on 15m at 50 watts max power for my callsign/greece /united arab emirates/japan on 15m/
some people /hams say its horrible because of its looks ..but if u have limited space like i have ..THIS ANTENNA REALLY WORKS...i rate it highly as i have heard and worked stations never b4 heard or worked..my log book can verify that..plus any tvi/rfi problems instantly eradicated for me ..thank you steve webb/designer of this baby..it is now a pleasure to work hf and compete with the big boys with max power...i,m on the cobwebb antenna /50watts/yaesu ft1000 mp mk 5 field and i can now tx with the knowledge that the dx station i can hear may now probably hear me..
one note of caution ..it is worth the extra effort to get the antenna to resonate to your favourite portion of the 5 ..yes ..5 bands where u normally operate from...keith 2e0jkd..i like it!!

A clever antenna idea
|
Time owned: more than 12 months
|
This antenna "does what it says on the box". It is the equivalent of a standard dipole on the bands that it covers, except that it's quieter on receive, and has no nulls off the ends. It's extremely clever in how it overcomes the problem that you get when you bend a standard dipole into a square...i.e the feed imedance drops to a very low value at resonance. G3TPW uses a T match system, that brings the feedpoint impedance back up to a comfortable match to 50 Ohm coax. I have built a homebrew version (using a recycled rotary clothsline as the frame) which works very well in comparison with a Cushcraft R7 , and other similar antennae that I have. It's ideal for someone with very little room for antennae.

nothing special

This antenna is well made and will last,but it is no better than my ocf dipole at the same height.I replaced the cobwebb with a mini beam which was much better on every band.Do not believe the hype on his web page

Excellent Antenna. OI have one now going into it's 13th yeardt
|
Time owned: more than 12 months

I now have th cobwebb going into it's 13th year. At this stage it is beginning to fail. The wires (dipoles) are all breaking where the wires are tied down on the cross members with cable ties. Some different method needs to be designed in order to stop.t this form of failure.
Howebr for 13 years it has done remarkably weel only having had to come down in it's 12th year for repairs
