    Enjoyed the review, just bought the antenna to give me something else to play with in my yard . . . XYL says, "No Towers" and she means it! Personally, I'm VERY happy to buy from USA manufactured ham suppliers.

    As a former manufacturing guy, it's nice to see products being produced in an American factory. To see the CNC machine tools and other capital equipment they have invested in, it's plain to see they are committed to this product line and building quality products.

    We are also a no tower house! There's no space on our property but also, it's hard to disguise an antenna tower.

    Really a fantastic team over there! I agree!

    After a storm eliminated a pine tree at the back of my lot which served as the far support for my 80m OCF dipole, I deployed the EmComm II. The 5:1 unum is mounted on my chimney, and the 60ft wire goes up to near the top of my 50ft mast next to the back of the house. From there, it slopes toward the back of the lot--which being more than 100ft away leaves the end of the wire about 15ft above ground. I still intend to tweak this installation. Nothing is currently connected to the ground lug on the unum, but the coax is grounded where it enters the house.

    Even so, the EmComm has outperformed the 80m OCF dipole on all bands (80-20m) with less than half the amount of wire in the air. I am seriously considering making this my HF base antenna and purchasing a second one for portable use.

    Was the 80m-20m antenna a Buckmaster by any chance?

    Not a Buckmaster. Also not exactly hombrewed, but cobbled together and very similar to NI4L's OCF dipole. Resonant on 10, 20, 40, and the low end of 80m.

    I just bought the Emcomm because I want to try a wire in a different configuration in a different part of my yard. I have a Buckmaster now, and while that is a "7 Bander" there are some compromises I'm sure, and I'd like to see what I can do with a sloper or some other arrangement in order to reduce band noise and perhaps reach out in a somewhat different direction I get a lot of Texas/Arkansas/Mexico/Central America for some reason presently (must propogate better in that direction).

    Comparing the 80m OCF dipole to the EmComm II, I think there are two primary advantages on the side of the EmComm.

    Number one would be better resonance on the 80m band. For the OCF to do its job on 40m and 20m, it has to be resonant very close to the bottom on the 80m band. This could necessitate a wide-band tuner above 3.9MHz.

    The second advantage of the EmComm (for me) is that less wire in the air means significantly less noise (and almost certainly a better pattern) on 20m, 17m and 10m. I live in a very built up area, and the potential sources of noise are in the thousands.
