FSL Antenna Combo Models-- the "Hong Kong Solution"


Gary DeBock
 

What can you do to chase DX on an overseas trip when all indoor locations have bad RFI, and almost all outdoor locations are overcrowded, making it difficult or impossible to set up a gain antenna?
You can push your luck with a "supercharged" 7.5" loopstick portable (if you have one), and if you know which stations to chase, you can sometimes do quite well (as Bruce did recently, during his trip to Israel and Jordan). But what if you want to boost your transoceanic DXing results with a gain antenna? You can attempt to set up a gain antenna on an overcrowded beach (as I made the mistake of doing in Hong Kong, ending up with a circle of 20 Chinese onlookers staring at me for the duration during the sunset skip session), or you can use one of these new, highly portable FSL "combo units."
These models combine a TSA-friendly small sized FSL (with the lightweight 100mm x 20mm x 3mm ferrite bars) and a stock portable (CC Skywave or XHDATA D-808) on a common PVC frame. There are three plug-in slots for the portable on the PVC frame, with secure rubber mounting clamps to lock the portable in place so that it won't fall out, even if the combo is held upside down. The  three plug-in slots provide optimal FSL gain for either the low band, mid band or high band, with the rubber locking strips designed to grip either the CC Skywave or D-808. The combo can be carried around anywhere, and provides a medium-gain option for those places which are overcrowded, or where gain antennas are impossible to set up (like Hong Kong).

The TSA-friendly FSL's include both 4" and 5" models. The latter model was the main antenna for the recent Poipu, Hawaii DXpedition, during which all continents except Europe were received on MW. The concept of having such antenna gain available to carry around practically anywhere should inspire a lot of exciting exploration in the future!

That is a neat looking setup Gary and a good solution to that issue.

Hi Gary,

You have again come up with an imminently practical and portable approach for ultralight DXing while traveling! The combo unit looks great!

Thanks Paul and Craig,

After our Hong Kong trip last April this FSL "combo" project was a top priority. Nasty indoor RFI and overcrowded outdoor areas are a bad DXing combination!

Of course someone chasing DX in Hong Kong right now would probably have a better chance of catching tear gas and/ or the Coronavirus, so it's no wonder that Cathay Pacific and Hong Kong Air are both on life support.

So you have any plans to make a step by step building guide?

Not right now, Paul.

The PVC frames for these combo units require some skill in gluing multiple PVC pipes and fittings, which is a little trickier than simply gluing up one FSL's PVC frame, and not common knowledge in the radio community. In addition, the lightweight ferrite bars in these original FSL combo models are the Russian surplus 100mm x 20mm x 3mm bars, which have not been available for purchase on eBay since 2012. There are some heavier ferrite rod substitutes which are readily available, however, which could provide a DIY option for others in the future.
