As for the past couple of years, the MMARC (Mid-MO ARC) will be using an ell-Elecraft Field Day setup.
In past years, it was multiple K2/100s, then a combination of K3s and K2/100s, but this year, if everything holds together, we'll have four (4) K3s, one each at CW, SSB, GOTA, and 6M VHF. With several K2/100's as backup, if needed. Our antenna system is pretty simple: Multi-band dipoles (80/40/20/15/10) running North-South, and strung end-to-end, with about 50 feet of separation between the ends of the three dipoles. Having the antennas in-line and end-to-end helps up take a bit of advantage from whatever null might appear directly off the end of each antenna. In years past, we've used a mish-mash of Elecraft and YeaComWood rigs and always suffered from front end overload of the YeaComWoods, and the Elecraft's hearing 'hash' from the YeaComWoods... but for the past 2-3 years, using all Elecraft rigs, those two types of interference have been significantly reduced... to the point that sometimes we find ourselves operating all three HF rigs on the same band, with no bandpass filtering other than that which is built into the rigs themselves. Oh, we might notice a bit of desense, from the next closest HF rig, but nothing nearly as bad a what it used to be, and nothing to prevent us from operating wherever we are. If you plan to use multiple HF rigs at your FD site, remember that there's NO HELP of you're using verticals, and less help if you haven't taken some effort to minimize direct radiation fro one station's antenna into those of the other stations. If you have an automatic (e.g. auto-tune) transmatch installed in one or more of the stations, BE AWARE that RF from another nearby station can come in on (and appear as reflected power even though you're not transmitting on THAT radio) the antenna/coax of the auto-tune transmatch station and cause the transmatch to try to auto-tune...!!! So, TURN OFF THE AUTO-TUNE FEATURE before you start your FD operation!!! 73 and have fun.
