In reply to M6ADB:
Andrew I agree with you completely, and congrats on the nice QSOs. There’s a rule I read somewhere that says that when it comes to antennas you can have any two of bandwidth, efficiency or small size. This one has narrow bandwidth, good efficiency and small size.
I also have a miracle whip (anyone want one?) which has wide bandwidth, small size and with which I’ve had just 1 QSO. Truly a dummy load, though not too bad as a listening antenna.
Back to the MP-1, I don’t know if it’s made much difference but I separated the ribbon cable into 12 radials immediately when I had it. I’ve been meaning to add a bunch of longer radials for ages but haven’t got round to it - will be interesting to see how much difference it makes, should give a couple extra dB. HFpack also reviewed the MP-1 favourably in their vertical shootout, the only thing that convinced me into buying it after my experience with the miracle whip.
I still use dipoles, inv-V dipoles, doublets, long wires and a few half wave end fed dipoles suspended from a kite amongst others, all of which have the edge, but the MP-1 is only a very small compromise. Just about perfect for mountain topping. The 817, antenna, mic., key, notebook (rite-in-the-rain paper is amazing by the way), pen, SLAB, power cable and coax fit perfectly in a small waterproop laptop case and I can change bands in the warm and dry from inside my Akto, antenna up through the door vent.
SOTA DX forever!!
