Homemade Carolina Windom antenna

Here is my home HF antenna It is an off centre fed dipole with 10 feet of vertical radiator It needs no tuner on 40m 20m and 10m It also works fine on all bands above 40m with a tuner and even below 40m on 60m and 80m although the coax losses will be higher

2020-1-1To interface the Splatter View between the exciter amplifier and antenna use the high quality UHF male to male connectors and shielded jumper cables provided Connect the model RF-D (RF Demodulator) directly to the output of the transmitter via the UHF male to male connector provided (Choose either SO-239 connector as they are bi-directional)

2017-4-30Here's the antenna pattern when compared to a dipole: Blue = Cobwebb Red = Dipole So as you can see above the Cobwebb has more signal strength over a large majority of the antenna pattern when compared to a dipole The Cobwebb is a closed loop design and it's also a quieter antenna This often results in hearing signals much clearer too

When the weather conditions are right (mostly due to Solar activity) you can talk around the world with as little as 10 Watts! I remember one time I was using a little 10 Watt radio and heard a pile-up of high-power (1 000 Watt) stations on the

2015-7-28Ham Hints Humor Ham Radio News! Post Reviews Product Reviews Ham Radio Videos! I would like to share with you my findings and my design of the well known vertical collinear antenna by looking at the work of two other hams: and added another 1/2 wave element and ran the coax thru the ferrite beads 3 times at 38 as per the calculator on

Antenna Terminology Defined

Antenna theory and antenna terminology can seem complicated to the uninitiated A lot goes into designing antennas but with a little bit of guidance and explanation antenna users (network designers systems integrators end users) can read through the antenna specifications and choose the right antenna style for their wireless network design

2020-7-3One of the most popular antennas today is the end fed antenna due to it ease of installation portability and stealth in various installations It can be a condo dweller's only access to the world of ham radio or the best alternative for a backpacking SOTA (Summits on the Air) mountaintop expedition

Our UHF Slim Jim Antenna delivers up to 6dbi of gain on the 440 - 470 Mhz UHF bands which is almost twice the gain of a J-Pole and 5 times the gain of a 1/4 wave ground-plane antenna Plus the antenna also have the great low noise floor and wide bandwidth typical of our other antennas

Ham Radio Contributions to Communications Technology Amateur radio history was made - and is still being made - by countless unique individuals throughout the world The Stuff Amateur Radio Operators Are Made Of It takes skill and patient determination to first study and pass the exams to obtain the coveted ham radio license

DX Engineering receive antenna systems feature the best designs available for HF DXing as well as for "AM DXing" on the MW Broadcast Band and for the Short Wave Listening bands (SWL) Maximize your signal and minimize noise with antenna accessories such as antenna switches vertical add-on kits variable phasing controllers baluns radial

Many Ham use this antenna in Russia and Ukraine with good result for local and Tropo QSO Easy constructions and good gain : 2 8 dbd in 2 meter band and 5 2 dbd in 70 cm band I used this antenna for SAT QSO via VO52 with good result Articles: RADIO 06/2006 and RADIO 03/2009

Note : It is quite possible that other calculators deliver slightly different results Some are based on look-up tables some completely hide their algorithms We use an interpolation approach Our results are optimised for gain but others may be optimised for bandwidth

Later we had Ham Radio Center ( Bill Du Bourd orig from Walter Ashe- Bill invented the 800 number and discount pricing) Midcom Walcom ham radio stores I myself even ran a ham radio store out of my 2-way radio shop for a few years Stu and Lou at Gateway were friends and mentors to all radio

73 Magazine (also known as 73 Amateur Radio Today) (OCLC 22239204) was a United States-based amateur radio magazine that was published from 1960 to 2003 It was known for its strong emphasis on technical articles and for the lengthy editorials in each issue by its founder and publisher Wayne

2013-8-30The feed of the left antenna is on the bottom Make sure the feed for the right antenna is on the bottom as well The same applies for (2) vertical polorized antennas side by side If the antenna has a gamma match that goes to the bottom of the antenna then both antennas should be
