After a few more weeks of not getting on the air I managed to man handle the portable Hexbeam up to about 4 above ground level (Note: must get that tilt base sorted out) to compare it against the Cobwebb I have in the loft.
So before we go down the ‘It’s not scientific’ route. I’m ok with that, no big deal its just a bit of fun.
There are some significant differences between the two antennas that I hadn’t fully appreciated. Firstly the noise levels on the Cobwebb were quite a bit higher, which seemed to make the Hexbeam sound quiet, when in actual fact there was no significant difference on the higher bands when it comes to S points. But, the lower noise levels made it much nicer to use. The image below shows what I mean. There is a band of ‘mush’ slap bang in the middle where I switched onto the Cobwebb. Just so you know, the Cobwebb was way quieter than the vertical I had before.
It’s not a huge visual difference on the screen but the ears make it obvious. The gain on the Hexbeam made it easy to make contacts with C06LA answering on the first call, I’d never expect that on the Cobwebb.
You can also see that the signal strength is fairly similar, that was W4UH calling CQ.
So not much in it when the Hexbeam is really low, I’m sure it’ll beat the pants off the Cobwebb at 12m but interesting to see that the Cobwebb is ‘noisier’. Especially as I thought it was quite a quiet antenna.
