Consider too, that old coaxial cable is likely non-shielded RG58
(or older) and could be the source of interfering noise that's worked its way into your radios and audio system.
For example, a 1.2-m length of RG58
cable has a capacitive loading of approximately 112 pF while the 1.2 m CP500x has capacitive loading of approximately 10 pF."
coax cable to the AC-coupled input of a LeCroy 1 GHz bandwidth Digital Sampling Oscilloscope (DSO).
12.7m long RG58
cable at 100MHz (equivalent to a line length d of 6.5 times the wavelength and an attenuation constant a of 0.0185[m.sup.-1])--and estimating the phase error at 1/8 of the wavelength away from the generator, gives [alpha] phase error around 13 degrees (i.e.
For the first simulation test, a wire network made of one junction and three transmission lines (RG58
low loss coaxial cable model) T (2m), [T.sub.1] (2.5 m) and [T.sub.2] (4 m) was evaluated.
As a numerical validation of the simplification method, a 9-conductor point-to-point connected cable bundle, 0.5 m long, set above an infinite PEC ground plane shown in Figure 4(a) is investigated, in which all conductors are braided CCs of the RG58
First, older airframes that haven't been upgraded might have old RG58
cabling that offers little if any shielding from stray noise that lurks in the airframe.
The smallest in diameter and the one with the most signal loss per foot is RG58
. You could expect to lose about half your signal strength with 50 feet of this cable between your radio and antenna.
Using a RG58
cable with a U/V stable polypropylene radome and 3M VHB Series two-sided adhesive gasket, Astron Wireless Technologies' LP8319H, LP8615H, LP8619H, LP9119H and LP9219H dual band antennas present a power handling capability of 50 W.
YOU CAN GO to any electronics store and buy a length of RG58
In the past, the company used RG58
coaxial cabling with BNC connectors at a speed of 10 megabits per second.
The plugs and jacks can withstand a temperature range of -40[degrees] to +110[degrees]C and offer a high cable retention force of up to 110 N for standard 5/50 cable (RG58
) and for 2.6/50 cable (RG316).
