Just testing out the 80m Inverted L on holiday in Cornwall. See if you can hear me, better still – call in!

▶️ Show-And-Tell: I discuss and even ramble(!) about some ideas and strategies how we might achieve some gain, follow the propagation and improve our stations – assumnig we don’t have a tower. This is not a complete discussion, for instance fan-dipoles are not mentioned and some other well known other antenna designs, (G5RV etc) and I also don’t discuss how to multi-band some of these antennas – I have discussed all of that previously. This is really about how to achieve for a) DX and b) daytime low-band 80m/40m (NVIS). Anyway, enjoy!

80m Inverted L: You could just as easily use a tree as a support – but I used a DX Commander Expedition Antenna and just grafted this on. PS Here’s the deal I was talking about: https://youtu.be/fCJdKMshhM0

PREVIOUS BUILDS:
https://youtu.be/nbBp42bbELo (3-element version)

I used the following element lengths:
40m: 11.2m (as original spec)
20m: 5.02m (as original spec)
17m: 3.83m
15m: (runs off 40m element)
12m: 2.88m (as original spec)
10m: 2.47m (slight cut)
*NOTE* Without 10m connected, I still got a tune on the CW end of 10m band – strange but true!
