Trans-Atlantic S2S Event - 4th November 2023 - pre-event chat.

The match location was not ideal, good DX take-off (and great sea views) to SW, W and NW but not on other bearings.

On Round 1 (10m) first to come out swinging was the EFHW landing some great punches with a clear 2-3 S-points ahead of the MPAS on most signals. This is not surprising as the 40/20/10 EFHW is optimized for 10m.

Very different on Round 2 (20m), going head-to-head, a lot of trading punches and duking it out, no clear winner, so a tie I would say. Maybe that’s because the MPAS telescoping whip (17’, 5.2m long) is optimized for a quarter wavelength on 20m and I use two wire counterpoises.

Long overs are good for comparisons: you get the chance to switch to the other antenna, use the ATU to load up on a nearby frequency and QSY back before the over is, er, over. There wasn’t enough activity on 18m and 15m to do this properly and there was no obvious winner. Not surprising as the EFHW isn’t designed for these bands and the KX2 ATU was doing its best for both antennas.

So, there was no knock-out punch and the EFHW won on points (S-points) for 10m. It will go in the rucksack for Saturday afternoon.

On the other hand, it shows the Cha MPAS Lite as a good allrounder for most bands, and when working 30-15m it’s done me proud many times when I needed a robust small-footprint antenna for a quicker deployment especially in very windy conditions.
