I just bought the uv5r and ordered some extras and now I'm not sure if this is what I need to increase the access of my radio. I just bought;



Falcon radio antenna FDP.2m

RG8X coaxial cable

PL259 Antenna connector

expertPower 7.56" Dual Band Two-way Radio Antenna. This looks smaller than what came with the radio. The manufacturer suggested the 14.4" model.



Please let me know if I should return any of this and/or what I should purchase so I may use my radio at home easily and also on a hiking trail.



Thank you.

Annette

Annette,

I'm thinking that RG-8X will work if your going to use to talk on repeaters but LMR-400 is a better low loss cable for your application. If you can afford it I would use the LMR-400 or LMR-400 Ultraflex

www.universal-radio.com/catalog/cable/3606.html

I'm not really sure how good a dipole would work on that radio?? I have the RHA-771 on mine and it seems that I receive less than with the stock antenna. The expert power one you have there would be ok but you might be surprised how good the stock multi band is that comes with the radio. I was.

PL-259 is for that use. (most common)

Maybe someone will help us out with the Dipole on that unit? I'm sure there are some really experienced HAMS on here.

Quick question, I have an external antenna and comparing LMR-400 vs RG-8X. My question is how much thicker is the LMR-400 Ultraflex vs RG-8X?Thanks��

It's not that much of a difference. The LM-400 Ultraflex is a little easier to bend that the straight LM-400.��--��"To err is human, To really screw up��requires a computer"

LMR-400 is 0.400" diameter.



RG-8X is 0.240" diameter.

Diamond make a dual band mag mount with LM400. I do not know if it Ultraflex. I am looking for the same. Since the diameter ��for LM400 is .4 inches how well would it work running it through the car door? I am thinking the door would squash the cable over time.��

There are several things that affect loss in coax. For a particular type of coax, two factors are frequency and length.



We are operating at VHF and UHF frequencies where there is a lot of loss. Little we can do about that.



Loss is given per 100'. Even lossy coax, say, 6 db at 100' is much less if only using 10' or so from radio to antenna, less than 1 db of loss.



I really don't think the low loss of LMR-400 vs. the stiffness and size is a good tradeoff at these short lengths. LMR-240 would be nearly as good, probably any difference would be unnoticeable.

I am not aware of any mag mobile antenna made with LMR-240. All I can find is RG58 and one with LMR400.What��is the thickness of LMR240 compare to RG58?

I beleive that most antenna manufacturers use RG-58 on mobile antenns (most, not all). Usually the runs (under 20ft) have almost no bearing on your signal. The placement of your antenna does. A magnetic mount sets up a poor ground plane and looses more, much more than the cable from what I've seen.



I use a BNC adapter and a Dual Band mag from (Import Communications) and the combo does a bang up job either in the White Mountains of NH or the lowlands of Florida. I have recently tried a few tests and found that lowering the power to 1W has no effect on most of my contacts through repeaters...... the radio does not get hot and the battery lasts longer........ that sort of tells me that the very minor loss in the cable is not worth the effort or the dollars.



IMHO
