17 Meter Coaxial Moxon Antenna - 17 m reduced size coaxial moxon rectangle, an exercise with an MFJ 259B plans by N0KHQ

50MHz J-Pole Antenna  ^pop - Need a general purpose antenna on the magic band? The J-Pole is an easy-to-build and inexpensive device that provides an omni-directional vertically polarised antenna without the need for a ground plane. In technical terms, it is an end fed vertical 1/2 wave which is fed via a 1/4 wave matching stub.

Double bazooka coaxial dipole antenna  ^pop - From WH2T Dr Ace's Double Bazooka Coaxial Dipole

EH antenna power lost considerations - Out of Balance Current or Longitudinal Mode Current in the Coaxial Cable causes radiation from the coax. But how large a proportion of the total power is radiated or lost from this Current?

About coax cables - General considerations about coax cables

J-Pole theory  ^pop - The J-Pole antenna is an omnidirectional antenna that can be used for base, mobile and field day stations. It does not need a ground plane, radials or a complicated matching system. The J-Pole can be cheaply, simply and quickly constructed using a variety of techniques, some of which are discussed in this article.

A Small Wire Loop Antennas for 160 meters  ^pop - Low noise, receive only coax loop antennas for 160 - 10 meters HF bands

Cebik Moxon Rectangles - The Moxon Rectangle is growing in popularity as a compact 2-element array that approaches a full-size 2-element in gain but with a far superior front-to-back ratio and a direct match for the standard 50-Ohm coaxial cable.

6m vertical antenna - G3JVL Six meters ground plane vertical is a compact antenna that is ideal for portable operations on 50 Mhz

IonoProbe - Monitors the space weather parameters essential for HF radio, including SSN/SFI, Ap/Kp, X-ray/Proton flux, and Auroral activity. IonoProbe downloads near-real time satellite and ground station data, stores information for future use and displays it in a user-friendly way.

M&P Audio - We are a new Amateur radio dealer. We carry products from Alinco, Hustler, Ranger, Antenex, Heil Sound, LDG, Uniden, TE Systems, Coax, and Radio Accessories.

ERP Calculator Plus - ERP Calculator is an Amateur Radio software utility designed to perform a side-by-side comparison of two Ham Radio antenna systems. ERP Calculator comes pre-programmed with data files including published data for several popular brands and types of coax cable as well as several popular antenna system brands and models. ERP Calculator displays values of ERP, Antenna Power Gain, Antenna Feed point Power, Antenna System Gain in dB, Antenna Gain in dBd, SWR Attenuation in dB, SWR Power Attenuation, Coax Loss in dB, and Coax Power Loss
