5. 10 1 Antenna installation 10 1 1 Fixed station For HF fixed station operation an antenna specifically designed for amateur operation is recommended An tenna types include wire antennas verticals rotary beams and other antenna types Fig 10 1 HF anten nas are quite large and must be installed to withstand strong wind heavy rain etc Any antenna used with the TS 440S 44X should be of 50 ohm impedance and should be connected using an appropriate coaxial cable such as RG 8 U Impedance matching is important Impedance mis matching will result in a high VSWR and power loss or can cause unwanted harmonic radiation and inter ference TVI BCI The impedance match can be checked with an SWR meter Generally satisfactory operation is assured when the VSWR Voltage Standing Wave Ratio is less than 1 5 1 A rotary beam antenna is very effective for DX com munication in the 14 21 and 28 MHz bands Fig 10 2 If open wire or balanced type transmission line is used with the antenna a suitable antenna tuner with balun is recommended between the transceiver and the feed line Methods of construction and operating such tuners are described in detail in the ARRL Antenna Handbook or similar publications For operation on the 160 75 and 40 meter bands a simple dipole antenna cut to resonance in the most used portion of the band will perform satisfactorily For operation on the 10 15 and 20 meter bands the efficiency of the stati
