An upcoming DXpedition (7-13 August) to Spratly Island 9M4SLL will consist of John 9M6XRO and Steve 9M6DXX who will be operating from a dive resort that closes at the end of August and doesn’t re-open until April.
Not optimum for the low bands but they stand a good chance of being louder on the higher bands than 9M0L.
Announcements on the various DX websites don’t offer much info in the way of what antennas will be in use but John was kind enough to take time to answer my questions via email:
We are going with two vertical antennas and we hope to put them as close as possible to the sea :(1) 9M6DXX has an HF6V-X with the 17/12m add-on kit so it covers 10-80m.(2) The second vertical will be based on the 43′ Vertical Monopole described in the July 2012 QST. It will have separate 5/8-wave vertical wires for each HF band from 10 to 20m with an ATU at the base. These wires will “float” when not in use, that is to say, only one will be connected to the ATU at a time (unlike a fan dipole). The same ATU will also allow us to match it on 30/40m.We will have an extension wire connected to the top of the 43′ vertical section to make it up to a 1/4-wave inverted L on 80. That extension wire will drop down vertically and be connected to the base of the 43′ vertical section when not in use for 80m.We will have a good number of radials laid on the ground for both ant systems.I have a Titanex V-160E but when we received permission from the Malaysian Govt it was too late to get it out there on a supply boat.
The 9M0L team used Spiderbeams and weren’t too loud at my QTH. 4W6A used verticals and were strong enough here to allow me to work them on 10, 12, 30, 40 and 80 meters with my dipole.
Thanks for the info, John, and have fun!
