ANTENNAS

-----------------------------------------------------------------------------------------------------------------------------

A 14 foot square Antenna for HF bands


Take a 57 foot length of antenna wire and place an insulator on one end.

Now put 4 insulators loosely on the wire do not secure them.  Secure the wire

at 56 feet in length to the first insulator.  Now arrange the 4 loose insulators

around the antenna at 14 feet intervals, these will be used to secure the antenna

when erected.

    Now take a length of 300 ohm feeder, either home made open wire or commercially made ribbon feeder, secure the feeder to the antenna at the fixed

insulator, making sure that the connection is well and truly water tight if

you use ribbon feeder.

   To erect, you can use it either in a horizontal or vertical configuration, but you must remember if used vertically, the direction of fire will be through the antenna, so you need to know your garden orientation with regard to North.

   Take the other end of the feeder and fix to a balanced ATU such as a Z match

or one that has balanced feed points.   Hoist the antenna as high as is possible

and tune.  This should cover 20 metres up to 10 metres.  Though the size is that

of a 18 mHz antenna.  See picture below.
