STAMPFL HAM Electronics X One Active Dipole Receive Antennas
STAMPFL HAM Electronics X One Active Dipole Receive Antennas are precision-engineered and designed for wideband coverage from 90kHz to 150MHz. Optimized to achieve excellent reception performance in a compact form factor, the X One antenna ensures exceptional RX signal integrity even in environments with strong RF density. The X ONE offers broad frequency range coverage and features high immunity to nonlinear distortion, delivering clean and accurate signal reception under challenging conditions. Its excellent common-mode rejection up to 60MHz minimizes interference, while an integrated FM lock, configurable via internal jumpers, enhances selectivity when required. Built for durability and ease of installation, the antenna measures 31.5in. in length and weighs in at only 1.98lbs., making it suitable for mounting onto masts with diameters between 1.57 – 2.40in. Power requirements are modest, operating on 12–14 VDC with a current draw of approximately 270mA. The X One features a Type-N-RF connector and includes a Type-N to BNC adapter for flexibility.

STAMPFL HAM Electronics VT5-S Active HF Receiver Multicouplers
STAMPFL HAM Electronics VT5-S Active HF Receiver Multicouplers were developed according to a design by Günter Fred Mandel DL4ZAO especially for SWL (Shortwave Listener) covering 9 kHz to 52 MHz. The VT-5S distributes a single near zero-Ohm star point (HF antenna input) to five outputs with a passive distribution network. This decoupling of the individual outputs prevents connected devices from influencing each other without level losses using a low-noise, high-dynamic RF amplifier and a push-pull output stage. These HF Multicouplers ensure high signal stability, minimal self-noise, and strong isolation between outputs. Additional protections include ESD protection on the input and short-circuit protection for the bias-T, which can remotely power active antennas. The VT5-S Multicoupler is designed to supply an external stabilized DC voltage . With an operating voltage in the range of 11.7 to 15VDC. The DC voltage must be free of hum and noise. The current consumption is approx. 150mA (at 13.8VDC). The DC supply is connected via a center positive 2.1mm ID (5.5mm OD) DC barrel plug. With its compact, lightweight design, the VT5-S delivers reliable performance for professional and hobbyist HF monitoring stations.

STAMPFL HAM Electronics Wave Block Preselectors
STAMPFL HAM Electronics Wave Block Preselectors are a precision-engineered RF filtering solution for the 0–30 MHz HF frequency range, designed to optimize receiver performance and protect sensitive front-end circuitry. Positioned between the antenna and receiver/transceiver, it employs eight switchable bandpass ranges to attenuate out-of-band signals, mitigating overload from strong sources such as AM broadcast stations. This results in a cleaner signal path and improved signal-to-noise ratio across the selected frequency range. Key features include low insertion loss (1dB), high dynamic range (IM3 ≈ 50 dBm), and ripple control within ±0.5 dB. The Wave Block integrates a 480×272 pixel TFT industrial display for intuitive operation, a bypass mode for full-spectrum pass-through, and PTT control via an RCA interface. Housed in a sturdy aluminum enclosure, the Wave Block operates on 9–16 VDC at approximately 200mA and includes built-in reverse polarity protection. Ideal for SDRs and wideband HF receivers, the WAVE BLOCK Preselectors ensures superior selectivity and guards against strong-signal environments.
