Not having a lot of space for wire antennas (50 feet at best) would it
be better for me to use an endfed zepp (50 feet) or a double zepp (25 feet each leg) ? On the endfed zepp there is one side of the latter line that its not connected to the aerial, on the other end (in the shack) where does that end connect to...ground or should it be connected just like any other latter line on the tuner ? Just trying to get the best results out of a small space. Thanks Gil |

A 50 ft end-fed Zepp would be 1/2WL on 9.36 MHz. The quarter- wave matching section would make it a three band antenna for 30m, 17m, and 10m. A 50 ft center-fed dipole will work all frequencies from 14 MHz up with a suitable tuner. -- 73, Cecil http://www.qsl.net/w5dxp ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= East/West-Coast Server Farms - Total Privacy via Encryption =--- |

Don't worry about the fact that up at the antenna, one side of the ladder line connects to the antenna and the other side is open. That was one of the best antennas that I ever had as a kid. Ideally, the length of the antenna should be 1/2 wavelength for this configuration.

However from a matching perspective the center fed arrangement will give you the easiest matching situation for the tuner to handle and less chance of unwanted R.F. in the Shack. I'd go for the center fed if possible. if not the endfed will work but may present you with matching problems on some bands. also you could allow extra wire to drop down vertically from the end in the center fed arrangement giving you a better match 80 or 40 Meters if desired. Make the total lenght about 88 feet and you'll have a good all band antenna. that would be 25 feet horizontal on each leg and 19ft dropped veritcally. Remember though any wire is better than no wire. 73 Dave |
