HF antenna

JPG Specifically designed for those with limited space, the Bushcomm SWC-100S is a shorter version of the popular SWC-100 model. It has a frequency range of 3.5-30 MHz and is an antenna designed and built for long life.

It is constructed with stainless elements that give it high resistance to corrosion.

Trees, buildings or other structures can be used to suspend the antenna, however it is best to avoid running the antenna over iron-roofed buildings. This reduces the effective height above ground, and, as with all HF antennas, the old rule "the higher the better" applies when wanting to extract maximum potential from the antenna.

The antenna can be mounted either horizontally between two supports or as an inverted 'vee' from either of the two sets of mounting points. Where there is plenty of space, the insulators at the ends can be used to mount the antenna between two structures (the total length of the SWC-100S is 34 m).

Where space is limited users can connect to the tie-off points at the top of the two small round boxes, in which case the remaining 6 m wire sections either side are brought down to the base of the support structures and secured. If mounted this way the antenna will total 22 m in length.
