If I remember right the velocity factor of LMR 400 is 85% and the velocity factor of 3/8 Hardline is 88% the velocity Factor has something to do with your receive as well as the transmit although 3% does not sound like a whole lot with weak signal receive it's actually more than it looks like or so I have been told
Ok , gp9 n is a 2m 70cm gmrs is about 68 cm Or so . what is your swr ???
Please look up 3/8s hard line cost was about $1.40 or so a foot . The difference in performance line loss and receive between helix Hardline 3/8 and LMR 400 will a amaz you
I had a friend who had a fancy HAM repeater and depending on what codes your radio sent depending on what other repeaters your voice came out of is that what he's talking about I wish I could remember the name of it
Oh ! on you hf question you could always go with a CB mobile one of the 10 meter brand CB'S a magent mount good CB antenna can easily be shortened to more than cover the 10 M BAND
The 6m band has an FM part . You can can get ht's for FM 6m .but you whill need to up grade the ant. Ebay has ladder line ant's cut for 6 M FM an 18 ft CB coax jumper and a couple of adapters throw your ladder line up in a tree and start waiting for FM openings on 6 M it's fun .
I'm just trying to learn my way around the site and making a whole lot of mistakes doing it !
Yes I was comparing costs versus line loss I think I put it in the wrong spot though
With a little Google research you should be able to find an amateur radio club in your area most people in these clubs are more than willing to show you there radio's and answer as many questions as they can . And please remember if everybody like the same thing Walmart would constantly be sold out
With a little research you could find some local ham clubs most are happy to meet new people and would be more than happy with technical advice and test question preparation
Hi
You will enjoy the 10 M BAND it is now opening and IMAX 2000 or Antron 99 stick antenna 20' 30' up will work just fine and a lot of your 10 m c B's although frowned upon is a minimal investment to see if you like it or not
