REUTER RLA4GS LOOP ANTENNA
Ge dig själv en perfekt vårpresent!
Tysk kvalitet rakt igenom. En utomhusloop elektronisk styrbar (via kabel eller wifi). Klarar frekvenser mellan 20 kHz till 30 MHz. Fungerar perfekt. Endast monterad utomhus några veckor under sommaren.
Dags att börja sälja av radioutrustning och antenner då en flytt till lägenhet närmar sig – tyvärr!

”The RLA4GS is a cross loop receiving antenna for fixed outdoor installation. It operates broadband as a non-tuned active antenna with an integrated amplifier. The power is supplied via the HF cable. The two loops consist of coaxial cables for the symmetrical control of two differential current amplifiers with a low impedance input. The utilization of the latest components in the two amplifier branches guarantees very low intrinsic noise values and high intermodulation resistance. The two reception loops are arranged at an angle of 90° to one another. By adjusting the amplifiers, an electronic rotation of the receiving direction is possible. The outer jacket of the antenna elements is grounded on the amplifier housing and shields the actual loops (inner conductor) against interference radiation.
Specifications RLA4GS:
Single loop dimensions: Diameter horizontal approx. 770 mm Height incl. housing approx. 690 mm
Amplifier dimensions (W x H x D): 140 mm x 60 mm x 120 mm (without connectors)
Frequency range: 20 kHz … 30 MHz
Average noise level (without loops): <= -145 dBm/Hz (at 10 MHz) IP3: >= +32 dBm (2x -6 dBm measuring tone at 10 MHz) IP2: >= +80 dBm (10.0 MHz + 10.2 MHz -6 dBm measuring tone, 0.2 MHz measured difference tone)
Maximum output voltage: >= 1 Veff, 1 dB compression Supply via HF cable: +6.0 V … +13.8 V maximum +14.4 V!
Power supply: max. 80 mA HF output: BNC 50 ohm
Weight: <= 2.0 kg
Version RLA4GS The GS version differs from the standard G version mainly in its larger diameter. The loop elements here consist of 1 m long 12.7 mm (1/2") coax cables. Low-attenuation "Flex" or "Superflex" cable with a shield made of solid, corrugated copper sheet (100 % shield coverage) is utilized. This results in very high attenuation values against interfering radiation.
The increased loop diameter enables stronger reception on low frequencies. In conjunction with the amplifier version RLA4 from version "J" (standard in all RLA4 from November 2021) the lower cut-off frequency drops to approx. 20 kHz.
The levels in the range from 50 kHz up to the lower KW range are approx. 3 dB higher compared to version G with lower inherent noise power. However, the larger loop circumference also increases the self-inductance of the loops and thus causes a reduction in antenna current at high frequencies.
This is partly compensated by the much thicker inner conductor of the cables (lower ohmic resistance, reduction of inductance with increase of conductor diameter).
Overall, the reception performance of the RLA4GS above approx. 7 MHz (40 m band) is about the same as that of the RLA4G.”
