Those things are not cheap. I was looking around 1500 or less. That thing starts at $4500.

thanks everyone. the math is something to have. i think i will scale it for the max 30v charging ability.

thanks for the help guys.

I need to get voltage from a remote solar site that has a micrologic PLC and one dc input card (installed for other task). I want to use the open input to monitor the battery bank voltage.
 
Problem is the battery bank is 28vdc so I need to drop the voltage to the input card to at least 10vdc when the battery bank is at 28vdc. Does anyone know what value resistor to use for this? or how to figure it up. Or a commercial item to do just this.
 
Thanks

really no one has unsed or heard of an analyzer for 900+mhz??

I'm looking for an Antenna analyzer's that will operate in the range of 800-1000mhz or better.

Does anyone know where I can find a Good manufacture that sells one. I have looked around and seem find 2 GHz and above or 500 MHz and lower. I know someone makes one for the gap in between  

Velocity
DB loss
VSWR
Freq
Distance to short

These are the minimum features I’m looking for

It can be a standalone or PC based

Thanks

found one bad connection and problem seemed to go away. took the choke out anyhow. thanks for the help.

i have lmr-400 and nothing else. so i used lmr-400. again remote part of wyoming. 30 mile drive for RG-58 is not really worth it.

can you use the Yaesu ATAS-100 with other radios and still auto tune?

thanks
Nate

 the choke and coax are supported independent of the antenna.

 the antenna swr does not change enough on 10 meter to detect. on 6 meter the swr does change with tuning.

 i'm running a 746pro with the antenna tuner turned off. with it on it will tune but then it will tune about anything.

 i will check the coax bend limits. 2 inch may be to small. the connectors will be checked again. before i put it up i checked for a short and found none.

thanks

i have cut almost a foot off 1 inch at a time and not much happens. it is well over 3 on 11m

thanks

i have had an A99 in the air for something like 15 years. i ran one with out a ground plane for some time but got one from a friend for free and never looked back. in 2003 a sand storm in iraq slammed the antenna into the tarmat and broke two radials and i noticed a diff the moment i put it back up. so i made replacements. i worked the world over on the A99 with about 35 watts in 2003. in 2005 i returned to iraq and then to afgan in 2006 with the A99 in tow. the 10 meter band really died in 2005 but i still got a few contacts with it. AND, its the only antenna to make it threw the mail or military convoy that did not show up destroyed. i still have it today here in wyoming even after i dropped it from 35 feet.

I built a 1/2 wave dipole with a coax choke using LMR-400. the choke is about 18 feet of the lmr coiled on a 2 inch pvc pipe. the wire for the antenna is 16gauge copper wire, 8.4 feet long each side. the choke is about 3 inches from the antenna. total length of coax after the choke is 35 feet. Antenna in located 14 feet off the ground pull tight horizontally. choke and coax are 90 degrees from antenna (vertical)

First problem.

This set-up will not come close to tuning 10meter. it does tune 6 meter pretty well though. what gives?

Second problem.

Even on 6 meter if i raise my power more than 3-4 watts my SWR jumps past 3:1. I'm not one to run my gear past about 1.5-1.7 so this is not going to work.

Can someone please point out my mistake?  what’s going on here? I don’t have an antenna analyzer and the closest person around that does is more than 30 miles in either direction, joys of living in a remote part of Wyoming.
