|Customer Reviews for the MFJ-1895.|
|From: Rod Case Kd7qxo|
|Very good antenna! I put it up yesterday at about 30+ feet. I turned it west and easily worked several east coast stations who gave me 10+ RST reports. Today, Japan stations came in at 5-9. The materials are good and it was easy enough to build. |

|The MFJ Moxon 15 m antenna performs pretty much as advertised. The instructions are clear and the array goes together smoothly in one afternoon once the measuring technique is settled. Though not as sturdy as its 10m cousin from MFJ, when settled into its final mounted position it maintains itself at least through moderate breezes. |
I compared performance at 50' with a dipole at a similar height and parallel broadside. SWR at the specified dimensions is less than 1.5:1 over the entire band. From my EZNEC v5. model I expected at this height over medium ground properties a f/b of mid -20 dB, and a forward gain of +3.3 dBd ( 11.6 dBi @ 13 degrees elevation vs. 8.3 dBi at the same angle). I regularly observe stations on the backside of the moxon down by 3-4 S-units with respect to the dipole. The signals on the frontside generally appear brighter relative to the dipole but less than 1 S-unit. In summary the moxon performs as expected.
In practice I have received an unsolicited "Big Signal" report with 100 watts from a 3D2station in marginal propagation conditions ( sfi ~100 ) . Also with the moxon I rapidly worked VP8SGI on the first day their expedition in a heavy pileup running 800 watts. Note: I changed out the current choke on this antenna with one rated for 2.5 kW. Although MFJ rates it at 1 kW, I felt uncomfortable with the safety margin.
