SELLING International Antenna Company (IAC) - QRZ Forums
2021年10月11日 · International Antenna Corporation (IAC) started in 1992 later changed to International Antenna Company in 2007 to provide amateur operators with high quality efficient HF wire antennas. Since that time, IAC designed variations of our flag ship product the Double Bazooka to include Half Sloper, Inverted L, Shorty, Dual Band and Phased Array ...
Inverted L vs Double Bazooka 40 Meters WSPR 24-hours
2020年11月18日 · Over the past two days I have been running 24-hour periods of WSPR on both my Inverted L and Double Bazooka antennas on 40 meters. I realize there may be differences in propagation between two days, so it’s not a perfect comparison but it’s the best I can offer. Both antennas performed extremely well transmitting 200 milliwatts of power.
ZS6BKW Antenna Review: 1000 QSOs later... | Page 3 - QRZ Forums
2020年12月20日 · On 75m use a 10 to 1 tuner an it works like a non resonant antenna on receive ( great signal to noise ratio) but down 2 S units on transmit for a resonont dipole. to me that's a good trade, can switch it with a double bazooka I use also for 75-40m an with a flip on a switch an can still hear the distance contact a little easer most of the time ...
What are Zepp, Double Zepp and Extended Double Zepp Antennas?
2024年2月18日 · Zeppelin antennas were wire antennas that could be trailed behind the Zeppelin airship. As they were trailed antennas they were used in end fed configuration. Double Zepp is a center fed half wavelength antenna. Double extended Zepp antenna consists of two collinear 0.64 wavelength elements fed in phase. It has a gain of 3 dB over a dipole ...
MDSR station gets new antenna - results of WSPR propagation test
2014年9月5日 · We have upgraded the antenna on the MDSR test station. The G5RV was retired and replaced with a "Double Bazooka" made out of RG-58. This antenna is a horizontal dipole, but uses coaxial cable instead of antenna wire. The advantage of coax, instead of regular antenna wire is the reduction of the wave propagation inside the coax.
Gregory S. Morrisette, W4TUT SK June 16, 2019 | QRZ Forums
2019年6月16日 · Again with double bazooka antennas from International Antenna Corporation I purchased a new 20M, 40M & 80M element antennas and supported all three in a inverted V fashion from my 30 foot flag pole spaced about 5 feet apart. I like to call it my Christmas tree antenna. They work great and I have no interaction problem with zero SWR.
What's The deal with the NorCal Doublet? | QRZ Forums
2023年1月22日 · Nice experiment. Seems to be a another kind of a Bazooka-Antenna. The magic is in the fine tangle of wire. I tried something like that with a copperline with 60 veins and a diameter of 0,1 mm each. Here I build a 80M 1/2 wave helical. It worked as fine like the computercable, to that a phonic transmission wasnt a problem too. So a tuner is ...
How does that J-pole really work? | QRZ Forums
2020年10月28日 · It sounds like a VHF version of the Double Bazooka dipole, lots of smoke and mirrors. I built one decades ago from 450 Ohm ladder line and hung it indoors from an attic roof rafter to access the old DX cluster and some friends on Simplex. It did the job but my hilltop location did most of the work.
Uncomplicated Contesting: Nate N4YDU - QRZ Forums
2024年5月9日 · Good video and also very interesting Nate N4YDU's career as a radio amateur and as a contestant. On the other hand, (and I clarify that it is not my intention to disparage Nate's achievements or his value as an operator and contestant for our hobby), I personally believe that if a great operator has the good fortune of living in a geographical area that, due to its topography, and/or proximity ...
ZS6BKW Antenna Review: 1000 QSOs later... - QRZ Forums
2020年12月20日 · When I really got into the hobby in 2013 (upgraded to General) I wanted to get on the air in the HF spectrum. Bought the radio, Amp and needed an Antenna. I have limited space on my property and wasnt exactly sure what to do. A Ham friend and i built and rigged up a ZS6BKW antenna and I found success in working the world.
