For the ARRL 160 contest a few weekends ago, I needed a quick and easy way to get on TopBand from my Oklahoma QTH. I am in a very antenna restricted area and my back yard is only 50 ft deep. I purcha

I use four of the Valor 160 meter mobile antennas with my DX Engineering RX 4 square. The results are amazing. I purchased them from AES in Cleveland (they were in stock). K8AZ just bought 4 of them
I am no longer using the DXE active antennas. The active antennas worked fine, but in a multi multi with all of the RF from multiple bands, the active antennas were trouble (no way to put bandpass fi
I've had numerous off reflector exchanges with many of you concerning my mobile antenna RX DXE 4 square. W8JI's web site is full of helpful ideas on reduced size antennas. My other favorite reference
I am curious if there are directional improvements to be gained with Beverage antennas with respect to height above ground? What changes at 6 ft, 8 ft or 10 ft? How important is it to have the height
I thought using a cell tower was also a good idea. I used one in the late 80's during the ARRL 160 contest operating from Ohio. I used it to hang an inverted vee dipole with the center at 300 ft. Str
Hello Bill! I posted this to the reflector last December. It is a simple, easy and very effective antenna for 160 meters. Several operators have emailed me after building the antenna and they are hav
I can confirm that a low ½ wavelength dipole is VERY effective on 160 and 80 meters. Mine are 20 feet high for both bands. Before Sunset and after Sunrise they are often the best RX antennas w
I have recently had great success with the DX Engineering Noise Canceling Controller (NCC-1). For years we used the MFJ 1025 which worked very well. I was able to more consistently peak signals (incr
Hello Bob! I installed a four square receiving system for 160 meters using the RG-6 cable, connectors, stripper and installation tool all purchased from DX Engineering. I installed a connector in les
Here is a timely paper on 4 square measurement techniques that was presented in Dayton a few months ago: http://www.kkn.net/dayton2008/W8WWV08.pdf 73! Tim K3LR _______________________________________
I have used all four of these cancellers on 160 meters. The MFJ-1026, ANC-4, SEM and DXE NCC-1. The NCC-1 works the best for us, with the 1026 coming in second. I could never see any receiving improv
Dave is 100% correct. After seeing K1LT present a paper at Dayton 2008 where he used the W8JI short verticals in his 160 meter beam forming vertical array - I switched to them. Look at page 14 of his
Hello Dave: I am using two four squares for 80 meters. They are spaced 5/8 wavelength apart (broadside to Europe). There is 3 dB additional gain with two 4 squares compared to one. They are each fed
Hello Sante! The PowerPoint presentations for the Antenna Forum since 2004 are available on the left side buttons at http://www.k3lr.com The 2010 Antenna forum papers will be posted on the same websi
The four excellent papers that were presented last week during Hamvention are now online (Thanks to K5TR). The 2010 Dayton Antenna forum had standing room only attendance during many of the talks. Th
Hello Rag, You might want to check out the 3 ele parasitic vertical Yagi in the last two editions of the ON4UN book. It is very easy to assemble, but does require an extensive ground system under eac
Hello Mike! I do exactly this - raise the Beverage from 7 feet to 13 feet - on my 1100 foot Beverage - when it goes over the drive way (about 15 feet long). There is no difference in performance vs.
Hello Mark, As soon as you add a few 120 ft radials on the ground, this antenna will starting working better. The more you add (to a point) will even help more. Don't worry if they can't be all the s
