Here, in Central Mississippi, we have very violent storms and it's a bad idea to keep an antenna connected for several months a year. I use(d) a ceramic based knife switch (a BIG one) for normal use and threw te thing out the window when the air had "that feeling". Gray Shockley ---------------- DX-392 DX-398 RX-320 DX-396 CCradio+ w/RS Loop Justice AM Antenna Torus Tuner (3-13 MHz) Select-A-Tenna --------------------- Vicksburg, MS US Since I'm planning on running a random wire until I can figure out a more permanent location for a trap antenna that I'll build (assuming that I still have that old article from Pop Comm (or was it Audio?) lying around), I'm not so concerned about the antenna itself as some of the other goodies. First, the coax. I noticed that Rat Shack was running a special on their RG-58U coax for $0.11/ft, but I also know that RG-8 is has better attenuation numbers. My run of coax is about 60-70 ft or so (at least initially, I'll probably remove some of the built-in slack in my estimates once I'm satisfied with where the antenna will be). Should I worry about attenuation for the HF bands enough to use the RG-8 over the RG-58?? Second, a lightning arrestor. Are those Alpha Delta Transitraps as good as advertised, or should I stick with a regular gas discharge variety?? Third, has anyone run an external antenna to their Sat 800?? I'm curious as to your setup, since it's a plastic case and the old ground connection that I was used to on my old Icom R-70 isn't around, so I was wondering if anyone bothers to try to ground the outer jacket of the coax. (Yeah, I know that that ground on the R-70 was for the casing, and that this means we'll open a can of worms here, but I figure I'd ask anyway.) --Mike L. |

The "random length" is really, pretty much, the baseline against which all the others are measured but it's also just a darn good antenna, in and of itself. Actually, I was using that inside the house (just trimmed down to 20 ft or so). I stopped by Rat Shack to pick another one up, but they were out. (The sales guy claimed that they don't stock it much any more since it's seldom asked for. Probably if the store wants it, they have to actually sell it every once in a while for their computer to start ordering more.) So, I dropped by Home Depot and got 100 ft. of 14 ga. stranded copper wire and ran about 40-50 ft of it outside for the time being. As far as lightning protection goes, the best protection is the lead-in out the window and screwed onto a ground rod (or a coax connector that is melded into the ground rod if you're usin' coax).

I use(d) a ceramic based knife switch (a BIG one) for normal use and threw te thing out the window when the air had "that feeling". Ouch. For a change, this year in Cincy has been pretty darn tame for storms, but yeah, I can see doing that during the summer. By the time I'd go inside during the summer, a lot of the programs beamed at NA are already getting ready to sign off anyway. --Mike L. |
