After watching the YouTube videos made by Randy K7AGE, I soon ordered one of the Arrow II Antennas model 146/437-10 for $139 in July 2008.  It can be constructed quickly when in the field since the elements are screwed together after fitting the threaded ends through the mast.  Merely place the shortest element on the end farthest end working your way down to the driven element and reflector.   The 146/440 duplexer fits inside the handle with jumpers protruding to feed the 146 Mhz 3 element beam and another for the 440 MHz 7 element beam.  The internal duplexer is only rated for no more than 10 watts which is sufficient for most operating using an HT.  Most of the time when traveling, I use my Kenwood TM-D710A set at 8 watts in crossband mode and can easily work AO-51 and several more satellites.  An old medium duty camera tripod supports the antenna.  Before taking off on vacation, the different satelite passes are taken from the Amsat Site which is refered to when attempting to operate, esecially at rest areas along the way.  More than 10 watts can be used by connecting directly to the beams using the BNC fittings.  A popular rig having two antenna outputs is the Yaesu FT-847 where you can transmit and receive at the same time.
