Re: [HCDX] Remote antenna - is it feasible?

["Ken Alexander" <kpathai@xxxxxxxxxxx>]

   Hi Simon,

   If you could put a receiver out at the beach along with the antenna it would
   be easier to transmit the audio back to your shack.

   Use a receiver with a serial port (an R75?).  There are a number of fairly
   inexpensive wireless transceivers that send and receive serial data - like
   having a serial interface cable several hundred metres long.  You send the
   receiver commands wirelessly and have a small transmitter send the received
   audio back to you...sort of like your DX Tuner on a much smaller scale.

   Put everything in a tough, locked enclosure along with a car battery to
   power everything (and make it heavy) then chain the whole thing to a tree
   near the beach!  Then all you have to do is keep people from walking through
   your antenna.

   You might also consider a Wellbrook large aperture loop (ALA 100, I think).
   We use one on our Miscou Is. DXpeditions with great success, and it works
   very well on the tropical bands.  Install it near your shack rather than at
   the beach (I'm not sure the extra few hundred metres will buy you that much
   in terms of signal, but it might buy you some quiet!)

   73 - Ken

     >I'm envious of some of the great DX heard by Martin from Clashmore with
     his Beverage antennas.  At my Phuket QTH, I don't have room to erect a
     Beverage.  But there are miles of sandy beaches just 1 few hundred metres
     away where I could erect temporary antenna.  However, it is not really
     practical for me to sit on the beach all night!

     to a battery-powered pre-amplifier which would also include a wideband
     transmitter (low power, microwave), At my QTH I would employ a receiver
     unit to receive and downconvert the transmitted frequencies to their
     original frequency, (ie the medium wave band).

     signals over several miles.  But I am really looking for something much
     more simple that will enable such a 'remote' antenna to be realised.
