  • TK5EPs 4 square vertical system - OKDXF
    found that it's easier to make 1 of 2 more turns and measure the inductance You can then easily adjust the coil to the right value by removing a turn or 2 and stretch or compress the windings on the core
  • Switched-inductor VCO based on tapped vertical solenoid inductors
    A new switched-inductor voltage controlled oscillator (VCO) scheme based on tapped vertical solenoid inductors is presented With tapping ports, various effective inductances are selected by switches for multi-band operation
  • Short Loaded Vertical - K7MEM
    This is very common with mobile installations where a 102" vertical radiator is resonated with a loading coil to operate on the lower HF bands But a loading coil can also be used with stationary installation For example, the 43' vertical This vertical is often advertised as usable from 160 Meters to 10 Meters, with a tuner
  • Simple Multi-Band Vertical Dipole - DJ0IP
    This simple non‐resonant vertical dipole enables users with limited space to erect an antenna capable of being used on all ham bands from 80 through 10m It requires NO RADIALS Yet its performance is amazing for its size and simplicity
  • 4 square vertical system - egloff. eu
    This page is a short description of the four phased verticals system i've build and used It is primarily intendend to be used on the lower bands 160m, 80m, 40m All the principles stated here are of course valid for any other bands, but you can achieve the same game with yagi antennas easily
  • An on-chip vertical solenoid inductor design for . . . - ResearchGate
    A new switched-inductor voltage controlled oscillator (VCO) scheme based on tapped vertical solenoid inductors is presented With tapping ports, various effective inductances are selected by
  • Measurement and application of vertical inductors in high‐speed . . .
    The inductance per unit area is 424 nH mm 2, more than 1 7 times higher than other simulated spiral horizontal inductors Moreover, VIs have been applied in the design of a broadband amplifier leading to a 25% bandwidth enhancement
  • Tunable Magnetic-Core Inductor Based on TSV Vertical Switch
    In this paper, a tunable magnetic-core inductance based on through-silicon via (TSV) vertical switch is proposed The inductor has two tuning modes
  • A 4. 12 GHz, 3. 3 mW VCO with 87. 9% tuning range using a transformer . . .
    An 87 6% tuning range wide-band VCO with variable inductance is simulated The variable inductance utilizes 3 switches to deliver 4 different inductance values A body floating technique is used to mitigate the switches’ impact on the inductance
  • Xiegu VG4 4-Band Base Station Vertical Antenna | for HF Transceiver . . .
    Automatic band switching: The antenna has a single coax cable feed however each band is individually tuned with a low VSWR across the band Through fine-tuning, the best (rock-bottom) SWR can be achieved on the user’s choice of frequency within the band
