Usefull Antenna Cable?

[Lord of nothing]

Hi
I will buy an 400Mhz Band Antenna: https://www.delock.de/produkte/1468_Antennen/89627/merkmale.html
The is cheap, 400Mhz (Band) and high Gain. I need a 10m Antenna Cable to put it truth the Wall.

 :scared:I must send them an Email if the are for outdoor use to. if the are which one is better:

How about the loss are the low how the claim in comparison with other?
Thanks!

It really depends upon what your requirements.

What sort of loss do can you tolerate?
Will it be outdoors?
Any thickness/flexibility requirements?
Phase stability?
Cost constraints?

I often use HDF200 or HFD400 cable for fixed installations. It's a cheap alternative to LMR200 or LMR400. The 200 is lower loss than bog standard RG58, but because it has a solid central conductor it's not very flexible. The connectors and crimp tools are fairly cheap for this too.

Example attenuation figures at 450MHz for 10 meters of cable.
HFD200 - 2.2dB
HFD400 - 0.8dB
RG58 - 3.7dB
LMR600 - 0.6dB

the mentioned CFD200 has about 2,8dB loss for 10m @ 450MHz

another one to mention is the Aircell 5 with 2dB for 10m @ 432MHz, also 5mm diameter

as a compromise you could consider the Aircell 7 with 7mm diameter, still quite flexible with 1,3dB for 10m @ 432MHz

What sort of loss do can you tolerate?

I would guess the lowest is the best?

Will it be outdoors?

Yes and get into the Roof where directly under is my "Network" Cabinet and the Splitter.

Any thickness/flexibility requirements?

If fits in "normal" parameter thats ok.

Phase stability?

? 

Cost constraints?

What did you mean with?
I pay for the DELOCK Antennenkabel N Stecker > SMA Stecker CFD200 10 m low loss  cable ~17€ exclude Tax the other will be in the same range I guess.

The connectors and crimp tools are fairly cheap for this too.

I didn do that before. The Outdoor Cable must be rock solid because nobody can get there between early Autumn and late Spring. When the Roof get wet its to slippery and dangerous.

@HB9EVI
Hmm how got get a cable? I have nothing for crimping an what else is need.

hamradio supplies, shouldn't be a big thing to get; Aircell plugs are readily available for soldering as well.

I don't know about any 50 Ohm cable for dedicated indoor or dedicated outdoor usage; in CATV you avoid the white ones for outdoor due to the poor resistance to UV-radiation. Any of those cables will withstand outdoor usage.

Of course that doesn't necessarly include the connection between cable and plug, and plug and antenna. so get some self vulcanizing tape.

With CFD200 cable, you have 2,8dB attenuation, what means about half of the signal power is gone at the antenna plug

6dbi is not high gain at all, and antenna gain is often overstated.  That little "I" means isotopic.  While technically a valid number, it is often used in marketing to confuse customers thinking it's better than it actually is.  As far as cables go, at that frequency, I'd use something little thicker.  RG8X or above.  Larger the better. 

Having said that, all you need is what accomplishes your goal.  If this is a fixed location to fixed location communication, I'd use whatever works.  Sometimes RG58 is good enough. 

In my lab, I use anything from Andrew Helix to RG58.
