Blake Uk BLA-LP20K - 20 Element Log

20 Element Log-Periodic Group K Aerial

With "Twistable F" to ensure the F-Connector always points downwards to ensure weatherproof connections


For strong signal areas.

Can be mounted for horizontal or vertical Polarisation.

Solid build quality, stronger elements and a rugged construction.

Excellent log periodic impulse noise rejection.

Overcomes issues with 5G & 4G, specially developed to reduce bandwidth without using filters.

Moulded F connector in weather resistant rubber housing.

The F connector can be simply twisted into the required position (Vertical or Horizontal) with no need for any disassembly.

So, the connector will always be pointing downward.

The weather boot sits inside the recess of the F connector, making the cable connection very weatherproof.

Blake-Uk 20 element log-periodic group K refers to a particular configuration of elements in a log-periodic antenna. The log-periodic antenna is a type of directional antenna that can operate over a wide range of frequencies. The 20 element log-periodic group K is one of the common designs used in log-periodic antennas, and it consists of 20 elements arranged in a specific pattern.

The 20 element log-periodic group K consists of a series of dipoles of varying lengths. The dipoles are arranged in pairs, with each pair consisting of a longer and a shorter dipole. The longer dipoles are connected to the feedline at the front of the antenna, and the shorter dipoles are connected to the rear. The spacing between the elements varies in a logarithmic fashion, which allows the antenna to operate over a wide range of frequencies.

The 20 element log-periodic group K is designed to operate in the VHF and UHF frequency ranges, typically from 150 MHz to 800 MHz. It has a gain of around 8 to 10 dBi, and a beamwidth of around 40 degrees. This digital aerial is commonly used for television and radio broadcasting, as well as for communication and surveillance applications.
