  What is whip antenna? - a definition from Whatis.com
- A whip antenna is a single-element antenna that can be used with anunbalanced feed line such as coaxial cable,or attached directly to a wirelesstransmitter, receiver, or transceiver.
The whip resembles a ground-plane antenna without the radial system.The short, flexible "rubber duck" antennas found on handheld two-wayradios and cell phones are examples of whip antennas.
Inaddition, when a transmitting antenna is placed at a distance from humans and electronicequipment, the potential electromagnetic hazard is minimized.

  Miracle Whip Antenna
The Miracle Whip is the smallest and lightest portable HF whip antenna I have seen.
This would allow the whip to be removed, for easier carrying, as well as replaced, should it be broken, plus facilitate the attachment of short wires (longer than the whip) for improved performance when the opportunity arises.
I think Miracle Antenna should also consider making a version with an inline BNC connector, as it feels light enough to me that I would be happy to use it on the front panel socket of the 817 for convenient "walkabout" operation.

  Polk's Whip
The name ``Whip'' refers to a whip antenna, not a whip like a bullwhip.
Whip is simpler than other physics simulation packages for LightWave, allowing Whip to work interactively in Layout itself.
Its many applications include antennas, flapping handles, diving boards, wobbling objects, swinging ropes, car suspensions, pendulum-like effects, (and, well, we could go on.

  Antenna Installation
Antenna whip length and the length of the cables between the antennas and switchbox cannot be changed without degrading or destroying DF performance.
The whip antennas and the aircraft structure work together to form the directive antenna patterns necessary to the operation of the DF set.
Three things are critical to successful installa tion of the DF antenna system: (1) the length of the antenna rods, (2) the length of the cables from antenna rods to the switchbox, and (3) the symmetry and freedom from blockage of the mounting location.

 Whip and Mast
The antenna, obviously, serves as the antenna, and the transmitter's ground wire is connected to the support structure.
The whip and mast approach is an attempt to exploit the vague wording of 47 CFR ยง15.219.
According to the rule, the combined length of the antenna, the cable that connects the transmitter to the antenna, and the ground lead cannot exceed 3 meters.

 Active Antenna 2005   (Site not responding. Last check: )
Previous experimentation confirmed that it is easy to tune a short whip antenna by connecting it to the hot end of an L C (inductor and capacitor) tank circuit.
The high impedance whip antenna was "matched" to a JFET RF amplifier by placing a high value (1 megohm or greater) on the JFET gate to ground.
CV is dependent on several factors including the capacitance of the whip antenna, your RF amplifier input capacitance, your circuit layout, component lead lengths and variations in the powdered iron core and C1 and C2 capacitors values.

 Active Antenna   (Site not responding. Last check: )
An electrically short whip has a high input reactance with a very low radiation resistance, when connected to a piece of 50 ohm coax essentially causes a short-circuit and essentially no current presented to the receiver input.
A simple solution is to connect the whip antenna directly to a JFET with a high input impedance and a low output impedance or matching network for the 50 ohm coax cable.
Whip length and diameter critically affects the tuning of the tank circuit the antenna element is attached to.

 Whip Antenna   (Site not responding. Last check: )
I mount the antenna in the nose pointed forward well away fron all the electrical noise.
A full length whip will always be better than a base loaded for reception.
But a full length is always better (string or whip) when judged independent of sources of noise.

From the whip antenna systems used on the portable man-pack radios, to the larger vehicle mounted systems, even mast mounted extended range and long wire antenna systems.
Antenna - Similar to the AS-1729/VRC, this antenna is used with the newer SINCGARS FM radio sets AN/VRC-88, -89, -91 and -92.
This antenna is used for general short-range service and, because of its steel tape construction, can be folded into a small space.
