7B300W 1.8~29.6MHz Outdoor Shortwave Antenna HF Antenna 7+3 Amateur Bands High Gain Low Noise Level
Description:
It is a 7+3 band spider web shortwave antenna. Its 7-band is a full-size antenna with a natural resonance of 10-40 meters, and band 3 can use an antenna tuner to be a good antenna with standing waves below 1.5 at 60-160 meters. At present, it is possible that only this antenna is a 7-band full-size oscillator. Each segment adopts a deformation of the DP antenna, which is an omnidirectional antenna. There are 7 groups of parallel independent 1/2-wavelength oscillator, of which the 60~160m band uses the antenna It can be easily obtained, so it is called 7+3=10 band, with strong gain and low noise ratio 10-15db lower than the inductive antenna. 7 bands feature is full-scale natural resonance at 10-40 meters, and using an antenna tuner in the other 3 bands can make the standing waves of 60-160 meters in the amateur band below 1.5. The 7-band of this antenna is a full-size oscillator, and each section adopts the deformation of DP antenna, which is an omnidirectional antenna. It consists of 7 groups of parallel independent 1/2-wavelength oscillator, of which the antenna can be easily obtained by using 60-160m band.
A total of 10 bands, strong gain, low-noise is 10-15db lower than that of inductive antenna. It has a small footprint, light weight, easy installation, low environmental requirements, a height of more than 5 meters, and a surrounding distance of more than 6 meters from the antenna. It is suitable for bases and can be used in the field. No tools are needed when disassembling the antenna, which is convenient for field erection.
Using epoxy resin tube, stainless steel, ultra-high molecular weight polyethylene rope and other anti-UV materials, the antenna is durable. It takes about 20 minutes for two people to put up. Users can play in the amateur segment with one antenna.
