Re: [RCSE] Antenna Wire ???
The idea is to use multi strand for redundancy, other than this as long as it is as conductive as the OEM material it's performance will be similar.

Re: [RCSE] Antenna Wire
Been told that wire guage has no impact on reception, curious to know if that's true or not. Yes, it is true. But for mechanical reasons multistrand is preferred. Insulated is also not required but is preferred for both mechanical and electrical reasons. Generally speaking you can use most any conductor. I've used music wire too, when the installation lended itself to do so. I know one guy who used the burglar alarm window foil. But mechanical durability is often overlooked and just taken for granted. An installation can be thought acceptable when it's really doomed to eventually fail.

Re: [RCSE] Antenna Wire
No. The futaba service rep was quite specific in specifying the finest wire possible. We discussed using a single strand of music wire which he thought would be optimum. As I mentioned I have used such antennas for several years with excellent results. (that is my planes have not fallen from the sky due to antenna problems. When they did fall it was almost inevitably from pilot error) Robert Samuels..St. Louis From: Simon Van Leeuwen [EMAIL PROTECTED] I think what the Futaba service rep meant was to utilize lead material that has the highest strand count you can find. This, in an effort to increase mechanical integrity. I don't think he meant to say use the finest single strand wire...

Re: [RCSE] Antenna Wire
I can understand one strand of flexible wire being a problem, but piano, I don't agree with. The only way you're going to break a peice of piano wire is a sheering force that cuts right across the wire. If you've just broke your piano wire antenna, I'd bet that not your only problem. :) -Charles On Sat, 20 Nov 2004, Simon Van Leeuwen wrote: I think what the Futaba service rep meant was to utilize lead material that has the highest strand count you can find.

Re: [RCSE] Antenna Wire
I agree, but it would seem there might be a misunderstanding. If music wire were recommended that is one thing, even then not nessassarily the right ting the same reasons one should employ a stranded lead...single point failure. The way the original message reads, it is suggested very fine (thin, skinny, very small gauge) single wire was suggested as appropriate. I think it is not the right thing to be using. Tidbit: strand: single electrical wire conductor of some gauge (awg) lead: a bunch of electrical wire conductors bundled together to produce a conductor cable: 2 or more leads bundled together Charles Frey wrote: I can understand one strand of flexible wire being a problem, but piano, I don't agree with.

Re: [RCSE] Antenna Wire
I'll assume you mean single lead, and not single conductor. Any multi stranded lead from 26 through 22awg will work fine. Unless your application is on an extremely light aircraft (like a DLG), then multistrand lead is safer, as a failure of one or more strands does not result in reduced range...

Re: [RCSE] antenna wire size
Wire size is always put in relationship to its wave length 0.01:1 is a comfortable ratio. 0.001:1 may cause a mild concern of bandwidth. That will generate band selectivity and can cause some channel are more effective than another across the RC band. Over all wire size variation can cause much less impact than wire length (0.25wave on groundplane, 0.5wave air borne). Once again, we are using a ground base antenna in air borne applications that is electrically incorrect. I use 0.5wave across my 2m planes, or 0.5wave in "J" tips for my HLG. If CF is inevitable, we may apply "skin effect" on antenna theory. In principle, imagine a CF boom inside an aluminum tube-antenna. Majority of RF current flow at the outside surface of metal tube, that effectively making the CF transparent. knowing that the tail boom has a high aspect ratio, a practice 2nd best to the outside tube may be considered. That is to split a single wire into two equal length and run it outside the CF in all parallel arrangement. We would expect the RF one each paralleling wire to repel one another and concentrated at the far outer portion avoiding "seeing" the CF in between them. Any metal lengths or push rod MUST carry signal current "in phase" with the antenna current. That can be met by treating them in same fashion as a member of the team of split wires, except it stay at the core. However, all lengths must be equal to comply the "in phase" requirement. Aluminum strip with adhesive is one idea that comes into my mind at this point (only if you can make reliable electrical contact at all times without soldering connection). Copper although is solderable, some may think that is too heavy. I would use copper. When ever affordable, use 4 split parallel wire can produce improved result. The split wire ending near stabilizer need not be electrically connected together, but wire tips should not flare/diverge from one another by more than 0.05 of full wire "length". Dealers and vendor, can pay attention to this potential marketing opportunity, for "thin" copper foils with adhesive. :-).
