					<description><![CDATA[Recently, I created a slightly loaded 40m vertical with 25 ground radials. It seems to work very well although the receive noise is pretty lousy compared to my loops and dipoles, however on transmit, it does seem to work as planned; a typical 1/4 wave pattern that outperforms regular dipoles at low angles of radiation.   Be aware that [&#8230;]]]></description>

					<description><![CDATA[A successful morning today to convert my 40m vertical to an 80m vertical by adding a loading coil that I can switch out manually by just unplugging it. Nice and simple. It&#8217;s not a great SWR curve due to the loading coil but I achieved 1.8:1 SWR at 3.79 Mhz, ideal for DX. For the [&#8230;]]]></description>

					<description><![CDATA[I&#8217;ve been an addict of full wave (and partial wave) loops since realising many years ago that in comparison to a dipole, you get more bang for your buck if you build a loop &#8211; certainly you get more copper in the air &#8211; and loops are resonant on EVERY harmonic so a 40m loop [&#8230;]]]></description>

					<description><![CDATA[You may have a smallish back garden like me; 10m deep and 14m wide. Your 40m loop (that&#8217;s really 40m [or so] all the way around) will resonate on the 40, 20, 15 and 10m bands. Mine is only about 20 feet off the ground, around gutter height. Its not quite square but the far [&#8230;]]]></description>

We used the generator to power the FT1000MP MkV (200w) effortlessly pumping the hydraulic mast up to 10m with the SG230 bungee-strapped to the top, running one of our 80m dipoles across the top to [&#8230;]]]></description>

					<description><![CDATA[Vertical vs Horizontal: Overview: The first thing that I noticed was that during daylight hours, the vertical was utterly hopeless. Inter-G signals were virtually unreadable, to the point I thought it wasn’t working. Indeed, being daylight, I couldn’t hear a thing, just noise. Switching my NVIS loop in to circuit brought the band to life [&#8230;]]]></description>

					<description><![CDATA[I didn’t document fully last weekend that my 40m vertical experiment gave me a rather good match on 3.8Mhz. This gave me the idea of building a better 80m vertical this weekend by loading up both the vertical &#8211; and the radials. As I type this as I discover that first time up, I’ve achieved [&#8230;]]]></description>
