 ```The previous statement assumed that the antenna is set to the same band that you are transmitting on? Could the Orion be transmitting on a different VFO or memory by mistake. Perhaps you can test the antenna with a different transceiver to be sure. ----- Original Message ----- From: To: Sent: Saturday, August 28, 2004 23:58 Subject: Re: [TowerTalk] Perplexing Antenna Problem The problem appears to be in the antenna. Are the received signals strong and does it appear to have a proper beam pattern when you rotate it? John (callsign) KK9A ----- Original Message ----- From: "Bernard(wtrone)" To: Sent: Saturday, August 28, 2004 19:40 Subject: [TowerTalk] Perplexing Antenna Problem I posted the following message on the Yahoo SteppIR board and thought that I might also get some ideas on this board. I have an interesting problem for all of you antenna experts out there. If you have been reading this thread (Yahoo SteppIR board), you know that I have been having problems with my new SteppIR 3 element beam. I was able to borrow a MFJ-259B this morning and made a relatively extensive set of measurement, which taken as a whole, just do not make sense. In summary (2 measurements on 20, 1 on 17, 2 on 15, 1 on 12 and 2 on 10M for each series of readings): 1. Set of measurements using the MFJ with a 20" length of coax to the SteppIR. Measured from 20-10M SWRs of from 1.5:1 to 1:1 (also have the R and X measurements but won't go into those just yet). 2. Set of measurements using the MFJ in the shack using the full length of cable to the SteppIR. Measured from 20-10M SWRs of from 1.4:1 to 1:1. 3. Using MFJ to measure Coax Loss from 20-10M showed 1.3 to 1.6 dB. Probably about 135 ft of cable. 4. Put the cable in the shack directly on the antenna connector of a Daiwa NS-660PA SWR and Power Meter, and the SWR is 5:1 from 20-10M. The reading on the TenTec Orion is high VSWR. Take the PL-259 off the SteppIR and put it on a 50 ohm dummy load and the SWR is a flat 1:1 across 20-10M both on the Daiwa and Orion. 5. Tried varying the "tune" power of the Orion from about 1 watt to 50 watts. No difference. 6. Tried taking the Daiwa out of the circuit. No difference. Orion still reads high VSWR. 7. Swapped out a complete set of coax cables to insure nothing was common. No difference. Anyone out there in radio land have any ideas? I am going to talk to Jim on Monday, but this is really a STRANGE set of data. I am a bit perplexed with what I am seeing! 73, Bernard, WA4OEJ _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers", "Wireless Weather Stations", and lot's more.
