In reply to GW0DSP:
On the other hand a relatively short doublet and a small manual ATU
might allow HF operation from restricted spaces such as Tryfan, or
busy summits such as Snowdon! Even this may be unsuited to the more
difficult Scottish summits such as SS020, The Cobbler!
Having never deployed such an antenna on activations myself, I can only compare the linked, resonant dipole versus the doublet/atu set up from my own personal chasing experiences.
I always receive rock solid signals from the activators who use linked dipoles, the first ones who spring to mind are G1INK, GW4BVE, 2E0HJD, just to name a few, there are many more.
With the common use of the infamous FT-817, with it’s 5 watts, I would have thought that everone would automatically decide against using an atu of any description, primarily because of the fact that you want to put as much of the said 5 watts out of the antenna. This wouldn’t be the case when using any antenna requiring an atu, losses are inevitable.
Also, why include the added weight of an atu and patch lead/s when climbing a mountain?
Just my own thoughts, maybe I am wrong.
By the way, I am still waiting for a reply from my earlier question to you Brian…
Can you please explain your earlier comment on this thread, you have me baffled.
