apartment antennas and rfi
Those of you who are using apartment antenna I would love to know of your
experience. Now that satellite dishes are allowed on most apartments, is there a trend to use an MFJ loop antenna? What are the real results with QRMing satellite dishes? RFI in apartmements in general? I am sure that putting a loop where the satellite dishes go would work great. What power levels are people using in apartments. I don't think I would want a loop inside due to high voltages. Look forward to hearing from you all. 73, Alan VY2WU |

I'd stick to CW/digimodes and under 100 Watts. |

A good tuner helps.
What about getting your appt on the top floor, then you can squeeze something up top a dipole or two. you know there are a lot of computer programs that allow you the use of ham bands online. That is an option. Any trees around you could rap a wire around? Any grounded towers already on the roof you can shunt feed? Some nice omni albanders out there very expensive, just get them high as possible. Or go mobile, get one of those vehicles with huge antennas on and drive to the mountain top and do your transmitting there. Lots of possibilities. "dave" wrote in message m...

Those of you who are using apartment antenna I would love to know of
your experience. 73, Alan VY2WU I had a nice cw qso with a fellow in an apartment using a 9:1 unun made by balundesigns.com to a straight wire off his apartment balcony to a tree. Such a wire could be made very small and almost invisible, if that is a possiblity. Also, easy enough to homebrew your own 9:1 balun for such, if you are inclined. If you could feed with parallel line, an end-fed zepp might work well, but would require an end support, such as a tree, and the parallel is more visible. If the second support is not practical, many have used coil loaded verticals off a patio. This could be done with a collapsing fiber glass pole for removal when not in use. Both schemes would require a tuner. 73 ...Edwin, KD5ZLB __________________________________________________ __________ "Once you have flown, you will walk the earth with your eyes turned skyward, for there you have been, there you long to return."-da Vinci http://bellsouthpwp2.net/e/d/edwinljohnson |

I'd check at eham.com reviews. |
