Thanks again, everyone.
But can I damage G5 with an external wire? If so I'll use the whip inductor. Please advise.... Yes, you can, as most of these portable recievers do not have strong input protection, *nearby strikes can damage the input. *Don't make the wire longer then necessary and remove the mini plug from the radio in case of natural photo flash. You might add the inductor or resistor to lower the risk on damage because of built-up of static electricity. Wim (or anyone), So, an early post stated "the longer the better" but you say not so long. What is a good length to try? I assume I'll want to experiment with longer and shorter. Bought 24 gauge speaker wire, 100 ft. for $6.50 at Home Depot. But I'm nervous now, I don't want to do anything until I understand. I presume you mean, disconnect the antenna during storms with lightening flashes. OK. So, I'm thinking there are three kinds of potential damage from a long wi static, lightening, and overload from a strong signal. There are four ways to connect the antenna that I've encountered: miniplug into antenna out, alligator clip to whip, bare wire wrapped around whip, and inductive coupler (insulated wire wrapped around tube placed over whip). (Leaving the balun out for the moment) Am I right that too strong a radio signal (from too long a wire) can hurt the radio? I presume this is true anytime too strong a signal reaches the inside electronics. But my brother tells me the whip is connected to an internal amplifier that the antenna input jack is not connected to. So maybe the antenna input jack is safe in terms of overloading signal from the long wire. And maybe the inductor can also induce too strong a signal in the antenna which is then amplified, causing damage, is this so? So, connecting the wire via the antenna out jack and miniplug is safe with regard to overload, but inductive coupler, alligator clip on whip, and bare wire wrapping around whip (i.e., all connections to whip) are not. True? As for lightening, it seems all connection methods are dangerous. For static, all but the inductive coupler are dangerous. Right? Using a special transformer as mentioned in other postings gives you more signal output in case of short wires. So you can have a shorter wire (for example when you have limited space). I do not share the opinion that these transformers *reduce interference significantly. When you live in a residential area, you probably don't need this as noise will be dominant with moderate wire lengths. * More signal does not always mean better reception as noise will raise also. If I can figure out how to safely connect the antenna to the radio, then is a good way to solve this noise issue to use a very long wire? Or will it just pick up more residential EMG noise? I am in a residential area, I have apartment buildings on two sides, 100+ feet away, house on third side. Maybe tuning to wavelengths is the only way to get a wire to elevate signal above noise. Thanks very much! Jim |
