Motorola XTR446 & Standard HX750S

[yves]

XTR446 is UHF 0.5W while HX750S is VHF 6W.Try it in the forest and the motorola get better range than HX750S(I put in 6W):sad:
Is this normal?And where can I get a better antenna for the HX750S?
thanks.

Heard that UHF is better for obstruction than VHF,But is it normal that there is a huge difference?one is only .5W while the other is 6W!!

That's a little odd that the UHF radio is working better, but maybe for whatever reason the UHF signal is bouncing around those trees better than the VHF.

Does the VHF radio's antenna have an SMA connector or BNC?

BTW, you do realize that it's illegal to operate a VHF Marine radio on land like that, right? I'm not saying people don't do it...

Those marine radios have low power settings. Make sure you're at the full power transmit setting, and fully charged battery.

About the PMR446: these are not sold in USA because they run on ham frequencies 70cm 446MHz.

Yes I know it is illegal but I'm using in other country.BTW,what is an SMA connector or BNC?

SMA and BNC connectors.

Bottom image is a BNC

That top picture actually looks like an F connector

That is probably the reason for the tape measure below the SMA, it looks like a F connector but only about half the diameter
