CHA SPIDER ASB (Ham Sticks Not Included)
Turn your ham-sticks into 4-dipoles, with the CHA SPIDER ASB OCTAGON Antenna Spoke Base. No band switching required!
The SPIDER is an innovative, antenna mounting system, with a wide range of convenient mounting options, and accessories.
Enclosed in a weather-proof, die-cast aluminum case, using Lap joint construction, to provide protection against dust and rain; while providing excellent EMI/RFI shielding.
Please note that every installation will be different depending on the user and the user's location. You will need to have an antenna analyzer to make tuning easier! (seriously, beg, borrow or buy one, available here)
Tune each dipole independently! Also, please ONLY hand tighten the PL-259/SO-239 connection!
All hamsticks are compromised antennas and need retuning when moving across the bands. They are high Q and you need to find the sweet spot of lower SWR.
Using a rotator will give you a directional antenna and will null out some noise.
CONFIGURATON
The SPIDER’s octagon enclosure, uses 8 x 3/8-24” solid-brass connectors, to accommodate up to eight ham stick type antennas. Each set of Ham Stick antennas, form one-matched (dipole) pair; for one of four-bands; Positioned around a central hub.
Fed with 50-Ohm coax, the coax center-conductor, is connected to 4 antennas, one for each side of the dipole; while the shield is connected to the adjacent four antennas. Only the dipole tuned for the band in use will radiate. These dipoles will typically exhibit between 1 - 2 S-Units of directivity.
CHA SPIDER ASB
The CHA SPIDER ASB, comes completely assembled, tested, and ready for service. Included are detailed instructions, to assist the customer in achieving the most performance from their installation.
