Topband: Phased Short Beverages

[fmoeves]

Frank,Thanks for help.The property is on a slope that dumps into a creek then back up another slope. I don't think a 4 square would work i these conditions. I was surprised how well the short Beverages worked out.But wanted to try to do better. Last summer I was able to get up a 580' Beverage but it was bent to fit my lot.I just started using it and then i noticed the signal dropped. I checked the antenna and some critter chewed up the feedline. I replaced and it and it was quickly chewed up again. I didn't have enough time to evaluate it to see if it was even worth the effort. I may try again this summer but it had a pretty severe bend in it.I have considered the NCC-2Thanks again for the suggestions. 73Fred KB4QZH

Staggered Beverages only improve front-to-back ratio, they are especially effective whenused in conjunction with a DX Engineering NCC-2 controller.If you installed a single 430 foot Beverage your front-to backratio is still excellent and the 3 dB beamwidth is reduced to about120 degrees.Have you considered a Hi-Z (or a homebrew) 4-square receiving arraywith four short active or passive verticals?  Its performance is similar to a 580 foot Beverage on only an 80 x 80 foot space and far superiorto simple single loops.You can improve the broad 3 dB beamwidth of any small loop bybroadside phasing of two loops, but the required broadside spacingis 300 feet, preferably 350 feet.73FrankW3LPLFrom: "Fred Moeves" <fmoeves at twc.com>To: topband at contesting.comSent: Tuesday, January 12, 2021 5:55:59 PMSubject: Topband: Phased Short BeveragesWhile watching another one of Steve's(VE6WZ) awesome videos got me to thinking about doing this to with short Beverages...I thinking about end-fire phased where one stepped in front of the other.I have read what ON4UN has written on this subject and just how close you can have Beverages with out real problems with coupling.So has anyone on topband try this and what was your thoughts?Would it be a worthwhile effort.What about 2 loops,flags?Would it be better then a 300' Beverage?Anyway just thinking out loud and trying to improve my system.73Fred KB4QZH_________________Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
