vhf rang?

[bobbyb]

hi all, just a quick question.

what sort of rang should I get from my vhf radio. only 4 foot aerial butt mounted on roof of the boat. thanks rob.....

Depends on few factors. Quality of set, where the repeater is situated, weather etc. I have a GME with antenna thats seen betteryears n about to be replaced and have never had probs up to 50 odd NM out.

1. VHF is line of sight hence antenna height has most to do with range so work on 10nm ship to ship based on average antenna heights above the water, 25nm plus+ for direct ship to shore depending on shore station antenna height, the higher the antenna generally the better the range and improved with power output up to a certain point. 50nm direct ship to shore is not uncommon.

thanks guys, sounds good.

I git a Lowrance radio so should be standard.

No idea what you mean.

I think he just means he has a mainstream manufacturers unit (and presumably ariel setup) so he's expecting to be getting a normal sort of VHF range.

Ie in the middle of the curve....

Don't count on more than 20NM and you will have coverage. At times it can be way more than double that but it seems to vary a fair bit for a variety of reasons
