Balun 1:49 100W Magnetic Ring Barron F Short Wave Antenna Natural Resonance

Description

Description:
Features:
1:49 long-line dedicated balun
The main parameters:
1. The transformation ratio is 1:49
2. Input impedance: 50 ohms (unbalanced)
3. Output impedance: 2,450 ohms (unbalanced) suitable for long-wave short-wave antennas
4. Frequency range: 7/14/21/28MHz (after connecting 20m vibrator, it will naturally resonate in these four frequency bands, no need to adjust the day, no debugging)
5. Standing wave: less than 1.5
6. Power resistance: 100w (maximum 150w, SSB, AM, FM, CW)
7. Dimensions: outer diameter 50x130mm
8. Weight: 300 grams
9. Comes with epoxy resin plate, comes with 304 stainless steel lifting ring, and comes with a copper nose for the vibrator, which is convenient for users. The other terminal of the balun can be left floating.
10. Barron is already waterproof, and users only need to waterproof between the M seat and the cable connector.
This balun is especially suitable for field communication. For users who have no condition to set up the roof antenna at home, it is a good choice to use the balun to make a balcony fishnet antenna. The antenna operates in a half-wavelength state for the 40-meter band, operates at the full-wavelength state for the 20-meter band, operates in a half-wavelength state for the 15-meter band, and operates in two wavelength states for the 10-meter band. Therefore, the overall performance of this antenna is in the gain state, and it is terminal feed, natural resonance, free of debugging, and free of day adjustment. And the cost, finished product, debugging, and erection are particularly advantageous, and it is a good choice for novices and the wild.
Tips:
How can it be called a long-line antenna? Just pull a line? Do not! Strictly speaking, that is only. The name of the antenna should depend on the operating frequency. If the length of the antenna is exactly half a wavelength, it is called a Zibo antenna, also called a terminal-fed dipole antenna. The length of the antenna is greater than one wavelength, which is called a long-line antenna. More stringent, its definition can be summarized as: the antenna length is greater than one wavelength and is an integer multiple of half wavelength, which can be called long-line antenna. Then, when we use the same antenna to work in different frequency bands, the antenna is called differently? For convenience, we call the antenna working at the lowest frequency band a good long-line antenna.
Why use long-line antennas?
(1) It is not easy to set up an antenna in a city.
(2) A little gain, better effect than the dipole antenna in its maximum radiation direction.
(3) The direct direction is not obvious.
(4) The need for mobile communication.
Usage of long-line antennas:
Since it is a monopole antenna, the radio ground will better perform the performance of the end-fed antenna. Grounding problems, including the use of other antennas, must also be grounded.
Note:
Please allow minor errors due to manual measurement.
