215INSTALLATION AND CONNECTIONSN3ELECTINGALOCATION Select a location for the transceiver that allows ade-quate air circulation, free from extreme heat, cold, or vibrations, and away from TV sets, TV antenna ele-ments, radios and other electromagnetic sources. The base of the transceiver has adjustable feet for desktop use. Set the feet to one of two angles, to meet your operating preference. N'ROUNDING To prevent electrical shock, television interference (TVI), broadcast interference (BCI) and other prob-lems, ground the transceiver using the GROUND ter-minal on the rear panel.For best results, connect the heaviest possible gauge wire or strap to a long ground rod. Make the distance between the [GND] terminal and ground as short as possible.R 7!2.).'.%6%2 connect the [GND] ter-minal to a gas or electric pipe, since the connection could cause an explosion or electric shock.[GND]N!NTENNACONNECTIONFor radio communications, the antenna is of criti-cal importance, along with output power and receiver sensitivity. Select a well-matched 50 ø antenna and coaxial cable feedline. We recommend 1.5:1 or bet-ter of Voltage Standing Wave Ratio (VSWR) on your operating bands. The transmission line should be a coaxial cable.When using a single antenna, use the [ANT1] con-nector.#!54)/. Protect your transceiver from lightning by using a lightning arrestor.Antenna SWREach antenna is tuned for a specified frequency range and the SWR usually increases outside the range. When the SWR is higher than approx. 2.0:1, the transceiver automatically reduces the TX power to protect the final transistors. In that case, an antenna tuner is useful to match the transceiver and antenna. Low SWR allows full power for transmit-ting. The IC-7410 has an SWR meter to continuously monitor the antenna SWR.PL-259 CONNECTOR INSTALLATION EXAMPLESlide the coupling ring down.

113CE17INSTALLATION NOTESFor amateur base station installations it is recom-mended that the forward clearance in front of the an-tenna array is calculated relative to the EIRP (Effective Isotropic Radiated Power). The clearance height below the antenna array can be determined in most cases from the RF power at the antenna input terminals.As different exposure limits have been recommended for different frequencies, a relative table shows a guideline for installation considerations.Below 30 MHz, the recommended limits are specified in terms of V/m or A/m fields as they are likely to fall within the near-field region. Similarly, the antennas may be physically short in terms of electrical length and that the installation will require some antenna matching device which can create local, high inten-sity magnetic fields. Analysis of such MF installations is best considered in association with published guid-ance notes such as the FCC OET Bulletin 65 Edition 97-01 and its annexes relative to amateur transmitter installations.The EC recommended limits are almost identical to the FCC specified ‘uncontrolled’ limits and tables exist that show pre-calculated safe distances for different antenna types for different frequency bands. Further information can be found at http://www.arrl.org/.s4YPICALAMATEURRADIOINSTALLATIONExposure distance assumes that the predominant ra-diation pattern is forward and that radiation vertically downwards is at unity gain (sidelobe suppression is equal to main lobe gain). This is true of almost every gain antenna today. Exposed persons are assumed to be beneath the antenna array and have a typical height of 1.8 m.The figures assume the worst case emission of a con-stant carrier.For the bands 10 MHz and higher the following power density limits have been recommended: 10–50 MHz 2 W/sq m6ERTICALCLEARANCEBY%)20OUTPUT 1 Watts 2.1 m 10 Watts 2.8 m 25 Watts 3.4 m 100 Watts 5 m 1000 Watts 12 m&ORWARDCLEARANCEBY%)20OUTPUT 100 Watts 2 m 1000 Watts 6.5 m 10,000 Watts 20 m 100,000 Watts 65 mIn all cases any possible risk depends on the trans-mitter being activated for long periods. (actual recom-mendation limits are specified as an average during 6 minutes) Normally the transmitter is not active for long periods of time. Some radio licenses will require that a timer circuit automatically cuts off the transmitter after 1–2 minutes etc.Similarly some modes of transmission, SSB, CW, AM etc. have a lower ‘average’ output power and the as-sessed risk is even lower.Versions of the IC-7410 which display the “CE” symbol on the serial number label, comply with the essential requirements of the European Radio and Telecommunica-tion Terminal Directive 1999/5/EC.This warning symbol indicates that this equipment operates in non-harmonised frequency bands and/or may be subject to licensing conditions in the country of use.
