Radio for this craft was a MHz based one, rated at 35 MHz..so, all we know such a radio need a long cumbersome antenna..so, we instantly thinks about powering the TX, ignoring about the power of RF above 1.2 watt..at 3 watt such hand held TX can stop a pacemaker almost..and prolonged exposure to such 3or 4 watt TX invites great dangers...gradually such exposure affects brain cells, and it triggers lack of brain co ordination, depression, head ache, later, diplopia, wrong gait..and many serious mal functions..so, a radio shielding vest is a must..and not feasible to operate such powerful radios in hand held mode..surely must use it all with antenna system with counter poise..so, can we sit in vain because of that..? who..? never..must find a remedy in long usage..so, its too safe to add a flange/ cage antenna as tuned resonant, with an input booster..can make simply with hand held components..can alter frequency to our needs, can calibrate the out put with a a hand made field strength meter..
so, can see the simple set up..a flange antenna..and a tuner amp with frequency tuner..its designed for 26 MHz to 200 MHz almost..and i sliced the wire of antenna of RX, and soldered it to the out put of the booster amp..result..infinite range.. :thumbsup:
