I guess it is a good time seeing that the US$ has gone down against the Aust$. Do you have any recommendations as to an antenna supplier. Cruising is great but there is no time for play. Tony S/V Ambrosia Before you spend real money Tony, I'd suspect the fifth component. The smd devices marked 221 should be resistors, each with a value of 220 ohms. Four of those, effiectively connected in parallel, would give you the 55 ohms you are measuring on the multimeter. The fifth component (unmarked) is most likely a capacitor and would be more liable to be permanently damaged by the water. Difficult to test with a simple multimeter unless it also has a capacitance range(s). If you measure across it, it should read some very high value of resistance (greater than 10 M-ohm). I don't have any idea what it's value would be, but could be around 100pF (picofarads). If you are up to replacing smd components and can get one, (should cost less than 50cents) you could try replacing that. "Me" may well be right that the lacquer coating you applied has totally detuned the antenna, so all the above may be a waste of time. Regards Vaughan Henderson Vaughan Thanks for the advice. Antenna is now working after finding local technician who could test it. Apparently replaced the capacitor. Works great. Problem now is the length of the cable from antenna (on top of mizzen mast 12m up) to the phone. Overall run about 18m. Signal using RG58 is almost on existant. Using 6m Microwave cable and 4m RG58 get good signal. Love to have the antenna at the top of the mizzen. Would a total of 18m (with connection) made up of 6m Microwave cable and the remaining 10m of RG 213/U give me adequate signal. What is the option of a masthead amplifier.? I know there are heaps of questions but I am technical enough to be dangerous!!! Regards Tony S/V Ambrosia |
