Now the higher HF bands are waking up let’s look at an antenna with a small footprint that more than punches above its size. Engage with my channel by subscribing and commenting. 73.

Steve Webb is my grandad. He doesn't talk to me about it really and only heard about the cobwebb from my mum who used to do the soldering.

Hi Tim, I’ve had one of the Steve Webb originals for quite a few years now and been very happy. It does sit on a crank up mast so I manage to get it up to 35 foot. When not in use it just sits above the ridge of the roof, not very visible to the neighbours. Highly recommended. Thanks for the vid 👍🏻👍🏻👍🏻

Very good Tim! Interesting type of antenna, with lots to recommend it ,small footprint, resonant multi element with no rotator required and pretty easy to make your own! I've read lots of reports suggesting they work well without having to be at great heights, It would be interesting to do A/B testing with two identical Cobwebs at different heights. 73, Tom

I have had a Cobwedd up for around two years now. My is the the MFJ -1835. It took a but of reworking when I bought it (new from a local emporium). It is the single wire version. I have since re-strung it with good quality wire and paracord. It is now great and resonant on most/all parts of all the bands. 73

Great video, yes I have one and it is (was) the best omnidirectional antenna. Where there is a lot of light there is also shadow. 1. Very narrow band. 2. extremely sensitive to moisture and 3. very sensitive to a lot of snow. Mine was totally destroyed this year and the elements were completely pushed down. And now I'm thinking about whether I should buy or build one again.

Hi Tim. I have to assume all is well on the C19 front and no worries. Nice looking shack and I bet it will look really great when you have fully moved in. I cant really get HF at my QTH simply because I have a really small garden and a overly cautious XYL HiHi and even a glorified cloths lines is out of the question. Thanks for sharing and Im sure there will be those who will give this antenna a consideration. 73

Hi Tim ! Glad to see you are well and thanks for another fantastic video. I was wondering with your new 'shack' you could do something on cable management/keeping cables tidy. For a computer this is straightforward, but with a transceiver, computers and all the other wires/connectors, would love to know a good way to keep things tidy and safe/working for radio use. My shack is amess of cables and i cant find a good video on amateur radio cable management anywhere !

@timg5tm9412 жыл бұрын
A cobwebb is 8 feet square so you will need a decent attic in terms of space as you will need a good few feet of clearance from the antenna. I have seen a few designs for fan dipoles in attics - you can zig zag to fit in 40m for instance. OR you can feed as big a dipole as you can fit with ladderline to an atu via a 1:1 or 4:1 BALUN and multiband that way. Hope that helps.

Hi Tim. Great video put out just when I was thinking of making one. Out of interest, as I am very limited getting any height to an antenna, if this was 4m high would it show some NVIS characteristics? Look forward to seeing the finished shack. 73. Liam GM4VYQ
@timg5tm9413 жыл бұрын
Hi Liam like any dipole the nearer to a Halfwave in height the lower your take off angle (unless you go appreciably higher than half wave in height which can cause Nulls as well as lobes). At 4m you are nearly a Halfwave on 10m. You’ll still make contacts and occasional DX at that height even at 20m. 73
@ynot64733 жыл бұрын
NVIS only works up to about 8MHz, so this one isn't applicable to that kind of propagation.

Hi Tim,would the cobweb antenna at 35ft beat a hustler ground mounted vertical for dx?? Hustler works great but want better and no room for a hexbeam as already tried that.cheers
@kevhaworth53132 жыл бұрын
Verticals need good ground systems or be close to saltwater to excel. Try between 16 and 32 radials as short or as long as you can get them, more short ones are better than a few long ones. You may notice your SWR goes up, this is down to ground losses being reduced as the efficiency is improved. It also depends on the bands you want to work. I have a Cobweb at 35 feet and If I can hear a station, I work them. I also use verticals close to or over saltwater, they are superb performers then. If you can't get close to the sea, this is how a 1/4 wave plays over a VERY good ground system, 100 plus radials. kzbin.info/www/bejne/e4imhYNrYtF-abs
