We made this element a couple of weeks ago. 5m (about 20-ft) at heighest point coming down to 1m (3-ft) off the ground. 19.5m (64-ft) total length for a tune at 3.7MHz with more than 200kHz bandwidth. If you want say 3.8MHz and above in USA (say), aim for 61-ft. Deploy and test! Callum.
This time I brought TS-590SG, 700W Amplifier, 100Ah battery, Victron Charger, DX Commander Expedition, laptop, cameras, interconnects, USB hub, broken coax, Pro 7 headset, spare patch leads and more. I must be bonkers.
▶️ 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!

In brief:
* 18m Signature (£599): Guys at 2 x levels – think of it as a "low-band" antenna, ideally 80m-15m (but will work on 10m and 12m)
* 12.4m Signature (499): Guys at one level, 6m radius, does all bands 80m through 10m (tunes on 6m)
* 9m Signature: (399) Guyless – comes with a ground post – also 2 x reels DX10
* 10m Classic kit: (£299) Guys low-down. Comes in 2 x variants; 40m or 80m. The 80m kit comes with 2 x reels DX10 (at a discount)
* Rapide: £289 with ground post) Can be guyless with the ground-post option. 40m (or 30m) to 10m.
* Expedition: (£299) Suitcase size: 40m to 10m. No 30m option but can do 80m (and 30m will work on ATU)
* Venture: (£199) Economical: 3 x elements, will tune on all-bands (not 80m.

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
