New Antenna for Home QTH

Ever since picking up my IC-705 in October 2021 I’ve been dining out on location rather than configuration, at least where the home antenna is concerned; a random-length end-fed with a 49:1, slung up into a tree next to the shack. I’ve had some pretty good contacts using this setup, working QRP far into Europe and occasionally pinging the ding-dong repeater in New York on 10m, but it was always a suck-it-and-see first attempt, a cheap way of finding out which bands I want to focus on before spending more money. I was still chasing my first transatlantic contact when I heard Russ VE9FI one evening in December but, unable to work him on my EFLW I quickly uprooted the IC-705 to the back patio, where my home made EFHW was doing WSPR duty. Blow me if I didn’t get an S5/5 @ 5W, nearly three thousand miles across the pond, on battery power.

An obvious solution would be to throw some more power down the wire, but at the back of my mind it was clear that the wire was the problem. And the power. But mostly the wire. So here I am two months later, with some very nice fibreglass poles and a hastily flung resonant 80m HW, buzzing with excitement at the changes brought about by some fairly simple guying.

Yesterday’s initial attempt at stringing the 40m long stealth wire across the garden in a rotated L configuration produced more of an inverted V, thanks to the luxurious flexibility of my new poles, but adding some guy lines today actually enabled the vertical part to be truly vertical, and I think that’s what’s made the difference between the RF fizzling out at the horizon and providing a truly great take-off angle. All I know for sure is that I’ve not had any WSPR spots from Central America, West Coast US, or China until today.

Going forward I’ll probably add a second 2-section pole to hold the blunt end of the wire, replacing the far too flexible single section that I used as a stop-gap in fading light yesterday.

Another Go with 20m EFHW

I’ve now had three outings with my first self-built HF antenna, an end-fed half-wave on 20m twirled around a 10m squid pole. The main reason for this design was that I’ve got easy access to the kind of salty beaches that are supposed to work well as groundplanes, but with weather being what it is right now I’ve not had much of a chance to get out.

Today could have been such a day, but instead I decided to work portable from the car, perching myself on the Druidale Road above Ballaugh. There was zero noise floor and I was able to work pretty much every station I heard at 10W, with many of them giving me better reports than I was able to give them. The Swiss guys in particular were very strong with me, sounding as clear and loud as traffic on the local repeater.

There was a strong temptation to hang on a few hours and wait for the long skip to come in, but temperatures had dropped to 4℃ as the sun went down and I didn’t relish taking everything down without gloves and a torch. Maybe next time.
