| Subject: | Re: RF Antenna Help |
Don,
Your explanation helps me understand some of the practical considerations w
ith respect to coax antenna lines.=C2- Thank you. (RF has always been kin
d of a mysterious subject for me)
Next question:
As you can see from the photos, the center conductor is un-insulated and if
I install the C-ring, they will touch - that would be bad.=C2- Can I ins
tall a very short length of the center conductor insulation over that expos
ed center conductor?
I'm thinking that I could cut a ~3/16" piece of insulation (from the core o
f a length of RG-400), cut a slit in it axially, and press it over the expo
sed center conductor.=C2- And then, to keep it from possibly slipping off
due to vibration (I don't think it will, but just to be safe), can a put a
drop of CA super glue on it?=C2- Would that work?
TIA
-Jeff

The C shaped device is there to prevent an Impedance Bump. Impedance Bumps
can cause high VSWR, weak return loss, and poor system performance.
Coaxial transmission lines rely on a ratio between the diameter of the cent
er conductor and the ID of the outer conductor, in this case the ratio is s
ized for 50 ohms impedance.
Due to size limitations of the connector, it would be very difficult to mak
e the connection from the coax to the center pin of the connector without a
removable section. Reinstalling the C shaped section returns the transmiss
ion line back to the correct ratio.
Impedance Bumps in Coaxial cables can also be caused by pinching, crushing
and bending beyond the min radius,=C2- all changing the ratio between the
ID and the OD of the transmission line.

I have also been looking for the same, but have yet to find anything. Bussman
makes a 20 slot unit (B&C sell it), but it lacks the indicator LEDs. You can
buy fuses with built in LEDs, but they are a fair bit more pricey last time I
checked, however, that does address the need.

put them side by side and end to end? Not sure at this time how many spaces
I need, but I do know, I'll need more that 12.

Personal thoughts on the IWC Big Pilot Racing Works Edition
Blue dial, lightweight ti case, powerful mechanical motion - this should be perfect for me personally, but is it? replica mens watches (https://www.proreviewwatch.co)
Everyone acquainted with IWC Schaffhausen's iconic Big Pilot's Watch knows instant
consequences of such a big watch. Measuring 46. two mm in diameter as well
as 15. 4 mm high, often made from stainless steel and even precious metals, it's
a behemoth within the wrist. To get around this issue and make it more wear-resistant,
IWC introduced the Big Preliminary 43. While this solved the scale
issue, it also brought by using it some drawbacks, which Honest addressed shortly
after launch, along with another way around the big pilot's intimidating
stature. It comes in are the IWC Racing Functions version launched a few months
back. Since I'm slowly operating my way towards having my first IWC Big Pilot,
I wanted to get the hands on this one to see if We liked it.
To get away through the basics, the IWC Large Pilot "IWC Racing Works" edition is the same dimension as the steel or precious metal watch, but with a ti case and crown. This particular saves a lot of weight, that I'll get to later. In order to differentiate it from the normal range of the iconic Big Initial, it features a sunray-brushed glowing blue dial with gray numbers and hands. The quality and reliability 52110 that powers this uses a dual barrel program that still provides a 7-day power reserve, and is wound with a central rotor and built with a bidirectional Pellaton turning system for greater effectiveness. So in that regard, absolutely nothing much has changed. replica watches on sale (https://www.proreviewwatch.co)
I must acknowledge, I am a big fan from the Big Pilot and intend to add one to the range soon. While I haven't decided what type yet, I've narrowed that down to a few possible choices. First up is the traditional first generation Ref. 5002, which I had the enjoyment of borrowing for a while from the friend's collector. The originality of that watch, which I really like, is its fish-shaped overhead and closed bowl-shaped caseback. Following closely behind may be the "black carbon" IW506101, that is harder to track as just 100 were produced, and also admittedly a bit pricey consequently. Luckily, IWC threw us a curve ball with this IWC Racing Works edition! high quality watches replica (https://www.chronowrist.ru)
Thinking about my height of 2. 01m, I had no issues with the dimensions or weight of the Big Pilot. The steel Ref. 5002 weighs around one hundred fifty grams, which is quite heavy for any leather strap. Of course , this particular depends not only on the scale the case, but also on the movements inside. "Black carbon" Ref. 506101 significantly reduces bodyweight, as the material is approximately 5 fold lighter. This makes wearing them more fun, especially during the warm summer season. This IWC Racing Operates titanium watch should consider somewhere in between, but it offers so much more going for it which has me rethinking my perfect Big Pilot. best replica watches (https://www.chronowrist.ru)
So what captured my attention? For starters, the truth is that it's somewhere between the metal and carbon versions, when i like to feel the weight of the luxury watch on my hand from time to time. For example , I frequently wear an Oris Aquis depth gauge, which weighs in at 189 grams. That's on the rubber strap! Then there is the tactile look and feel in the matte titanium case. I simply love the purposeful, tool-like feel of a watch's appearance. Ultimately, the sunray-brushed blue switch won me over. In the beginning, I didn't think a lot of it because it looked like yet another random blue dial in my experience, but it offsets the Big Pilot's gauge design perfectly.
