RG213 vs RG214 Coaxial cable

Last night on freq 145.2125mhz (V17), we(9W2YED,9W2TLB,9W2SNA,9W2POK) had a discussion on air regarding on RG214 coaxial cable. Special thanks to Talib(9W2TLB) for brought up this matter. Most of us commonly use RG213 and physically saw how it looks like BUT what about RG214.........? What are the differences between RG213 and RG214?

RG213 (right picture) is low loss cable with a non-contaminating jacket.
General Specifications
Outer Diameter: 0.405 inches
Center Conductor: Stranded
Impedance: 50 Ohm
Outer Conductor: Braid
Velocity of Prop. :66%
Jacket: Black PVC-IIA

RG214 (right picture) is low loss cable with double braid and non-contaminating jacket
General Specifications
Outer Diameter:0.405 inches
Center Conductor: Stranded
Impedance :50 Ohm
Outer Conductor :Dual Braid
Velocity of Prop.: 66%
Jacket : Black PVC-IIA

Just look at it, the only different is the outer conducter (shield) whereby RG214 using dual Braid compared with RG213. I'm not sure the result of using RG214 technically because we're more common to use RG213 and easy to get at open market.

Please comment.

Perhaps someone should look into it, maybe actually use both cables and see the differences technical wise.. There must be a reason why they came up with the double braid.. Probably RG214 provides good isolation when you have more than one cable lying side-by-side.. This is my common sense speaking.. My technical knowledge is almost non-existing... lol :P

Yes, i agree with you, 9W2MIT. But for this cable RG214, it maybe hard to find it in local market, also the price maybe expensive too. Anyone who had experience or technical knowledge on this type of coax, could share with us the information, thanks.

214 is more commonly used in Satellite installs for the downlink side of a uplink antenna as not to radiate into the broadcast side. It is great when extra sheilding is required.
