[RCSE] Rubber Duck Antenna
From: Ron Quintana [EMAIL PROTECTED] Subject: [RCSE] Power/Rubber Duck Anyone had any experience using these in place of the OEM telescoping antenna? Yes. ~ 10 years with Futaba Txs (7UGFS and 9C). Haven't had a 'hit' yet. Is the range loss significant? No. Only problems I've seen are the same as with OEM systems - receiver antenna positioning especially in carbon/kevlar environments. Out of sight range with 3M ships. Good low altitude control with DLGs. Particularly useful (for me) with DLGs - helps prevent 'bent antenna' syndrome. There is some loss of signal but not enough to affect range in any way I've seen. Antenna lobe pattern is different but more favorable for pointing the Tx at the plane. Be aware that since these are not OEM, a CD can disallow their use - but I've not seen that rule invoked over the years. For the 9C, there's an installation article in the Feb, 2003 RCSD. - Dave R RCSE-List facilities provided by Model Airplane News.

[RCSE] Rubber Duck Antenna Pattern
Field test of a Rubber Duck vs a whip on page 6 of this newsletter. Keep in mind that our normal Tx grip has us pointing the antenna at the plane most of the time. http://www.propstoppers.org/pdf_files/june04.pdf - Dave R RCSE-List facilities provided by Model Airplane News.

[RCSE] Rubber Duck Antenna?
Has anyone used a Rubber Duck Antenna with the MPX Profi series of radios? I know the range will be somewhat reduced. I've range checked my Profi with the standard antenna collapsed and got 135 paces (appx 300'). When the weather clears I'm going to check it with a Duck and see what the range is...

Re: [RCSE] Rubber Duck antenna range
Please help me to understand what relationship of Vision, Stylus, Tom Overton antenna to a Ducky? Was that an antenna comparison test of same TX or TX comparison test of same Ducky? Or both? YK Seattle - Original Message - From: Jim Thomas [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Saturday, August 05, 2000 7:37 AM Subject: [RCSE] Rubber Duck antenna range I have seen the submission by YK Chan, and agree with the idea. I have done essentially the same thing with all new installations (first a Vision, then a Stylus). What I did involved a friend who stayed with the plane and had either a CB radio or a cell phone. By picking a long straight road, I then drove away with the transmitter, actuating one of the channels (rudder or elevator) and leaving the other for a stability indicator. When I got the extreme end of useful range my helper let me know. I then backed up until the signal was again strong and stable. When I tested my Vision with a Tom Overton antenna in 1991, I got 1.1 miles of useful range along an unobstructed country road in Indiana. When I tested my Stylus with the same antenna in Feb. 1995, I got 1.25 miles of useful range along a road in Seattle, that happened to have high tension electric towers alongside the same road. These tests were good enough for me, and I have used the antenna successfully on everything from HL to XC. In fact, I have never had the whip antenna on the Stylus since I developed the adapter to connect the antenna to the ball mount (just prior to the test above). I guess others must agree, I have sold over 200 of those adapters to Stylus owners that were tired of the whips. Jim Thomas (Stylus Adapter Boy) RCSE-List facilities provided by Model Airplane News.
