A lot depends upon the composition of your roof. Some are rather opaque to RF, and that goes up with frequency. Certain tile roofs are the worst, IMX.
OTOH, as Don points out, look at ways to get the antenna outside, even just marginally outside. A full half wavelength is only 10 feet lone (well 9.36 for 50 MHz), so a decent radiator need be only 9.36 feet long and 10 feet or so above the earth. Even if it can be only inches from some surface, such as your roof, it'll likely be better than anything in side. And it can be very thin wire almost impossible to see from a few feet away. If you can do nothing, try the current antenna, assuming you have open wire feeders to minimize the losses. That will at least give you a starting point. Ron AC7AC -----Original Message----- Maybe the cards are stacked against me, but I would like to go for the six meter band ssb. My problem is low power and attic location for antennas. Presently, I have a 66' piece of wire (center fed dipole) which works great (for PSK, CW and JT65-HF) using the ATU in the K3. I would like to get the group's opinion on antenna options or do I have to upgrade with the KPA100? Thanks in advance. -- Frank KD8FIP ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
