Looking for 465 mhz vertical
- Thread starter 555
- Start date
Depends how long tbe cable run will be. IMHO on tbat freq. if the run is much over 25 or 30 feet you will benefit from 1/2 inch heliax. That is unless the signals will be VERY strong like from a local repeater.
the tower is 72 foot to the very top according to my tape line
so 75 foot and then maybe another 40 or 50 into the radio room
at the present its running into the 440 beam pointed north about 30 foot in the air
if i do get a vertical then that will go on very top of tower
so far with the BaoFeng 5R on low power at 2 miles with standard dummyload antenna it will hit the repeater and come back at full strength
thats as far out as i have been today
going to pick up a sma to So-239 and hookit to this maxrad magmount and try it out monday
What would be a good commercail 460mhz vertical to use

For a run of 125 feet of RG-213 you are looking at a loss of 5.7 dB which means you are losing ¾ of your power on TX and the same on RX. Using LDF-4 ½ inch heliax cable your loss is only 1.8 dB for the same length cable which means you will only lose about 33% of your signal. You have to weigh the cost versus performance. If all you want is local repeater work you could probably live with the losses but you will have to determine that.
so theres a give and take part on this kind of setup
thought about running a length off my spool of lmr 600 uf from my beam install
but still the loss is kinda high.
and there goes that cost effective portion
so since most of my travel is north of my house i will keep the beam up and pointed north
will find out in the morning just how far this will travel
the repeater is only set at 12 to 15 watts out
