Nagoya UT-72G high gain magnet mount. I put a cookie sheet under it to ground. The cable is 10ft long. This is just a test setup, but this is my Achilles's heel.

Duplexer ? Antenna ? Feedline ? There is alot more than plugging a cable in and saying you have a repeater. How far away are they ?
I realize there's more involved than just plugging in cables. The SWR meter is 1.01, and 36.44 watts. The duplexer is an XLT, and the wires from the radios are LMR-400. The small gmrs antenna is a test. My friends are 8-10 miles away, and I'm on top of a hill.

Yes, input and output are the same tone for repeater.

I am having the same problem, did you get an answer?
As soon as you go to the link to locate your antenna. Drag the antenna in the center of the map to your location. Then zoom in closer, and drag the antenna closer to your location. MichaelLAX posted the maps which really helped.

So I have my radios hooked up as a repeater. I set the RPT-RX to a specific tone on one radio. I set the T-W-RPT to a specific tone for the other radio. I set my Wouxon KG-805 to repeater channel along with my baofeng HT's. Everything is transmitting and receiving on my end with all my HT's. However, I cannot receive or transmit with my friends.
I used the TSQL setting on chirp to be able to enable both CTCSS and RTCSS tones on the baofeng. But I can't transmit or receive with anyone outside of my own radios. What did I miss? SWR meter is at 1.01, 36.44W, and now I'm getting static after transmission.

I was able to better locate my antenna thanks to your advice.

I have added a repeater and I still can't get the "GMRS antenna" icon to move to the repeater's location on the map. It placed itself about 30 miles north of my listed repeater, Warren 550, in Warren, MI., when I listed it. WRUY699.
I followed MichaelLAX's diagram. You drag the antenna from continental map, and don't zoom into location first.

I figured it out. I made it harder than it needed to be. I followed MichaelLAX's diagram. You drag the antenna from continental map, and don't zoom into location first. Thanks everyone.

Trying to add repeater on mygmrs.com. However, when I try to drag icon to closer position it won't let me drag icon. Anyone know how to drag icon on map when adding repeater?

I went today and got a P.O box, and changed my FCC license online. How long does it normally take the FCC to update info? When does mygmrs.com website update my new address?

I now have the equipment to setup a repeater, except for my tower. However, I was gonna use a Nagoya UT-72G for a month or 2 until I get tower up. How soon can I add repeater channel to mygmrs, and can I update repeater after I have tower up?

The DB-404B is an omni-directional antenna, so there is no need to rotate it. Just put it on the mast. You only need to be able to rotate an antenna that is directional.
Freestanding towers are fine as long as you adhere to load and wind restrictions. Some tower manufactures have dual ratings, too; one rating if the tower is left freestanding and a second rating if it is guyed. If you are concerned, you should be able to contact Universal and see if they have any recommendations, if you think you are going to be on the fringe of the load or wind ratings.
Based on the description about the tree height vs the antenna height, you should not have any interference from the trees.
The person at Universal said he estimated 40' tower with DB-404B would have 1sq. ft. wind area. I mentioned the ice storm, and he stated their towers have held with 1/2" of ice. He also said if I wanted to add additional items down the road to plan ahead, and get a higher load rated tower. I feel better now. Thanks marcspaz.

I don't have experience with the 4-40 specifically, but I have owned a couple free-standing towers over the years.
What are your questions? I may have an answer.
Do I need a rotor mount? I spoke to a HAM friend today, and he said no. Decided on a DB-404B with OMNI antenna type. Horizontal beamwidth is 360. Vertical beamwidth is 27. My friend suggested to place tower close to home ground lug. Which puts it 20' from 40' tall pines. With a 40' tower and a 10' mast, and a 5' antenna puts me just above tree level. I'm on top of a hill to the north and west. I guess I'm concerned with the strength of a free standing tower, and how much loss from putting near trees.

I called DX engineering about a Universal tower kit. It's made of Aluminum. The only thing they had in stock was a Universal 4-40. The first number being for my area, and the last for the height of tower. Plus, they are supposedly self supporting. Has anyone used or is familiar with the Universal tower?

Rohn makes towers that hold up antennas. They have a tilt base that can be installed. I don’t know if Rohn makes a winch for it, but they’re pretty pricey. You still need an antenna to mount to the tower.
if I were you I would call Cushcraft or DX Engineering, tell them what you have, and ask what they recommend. I would certainly do that before sending the Cushcraft back and ordering a Rohn tower. The Rohn towers are free standing I thought, so no guy wires needed for most shorter heights but a poured concrete base is part of the installation.
Rohn also makes round tubing masts that would have guy wires or brackets depending on the installation.

They aren't made to go real high, and if a heavy enough breeze comes, she's gonna move on me. I'm thinking and hoping that if I'm gonna purchase a DB-404B, than I better make sure I make it as stationary as possible.

Thanks for the info. I noticed those towers are round and +50' high. I purchased a Cushcraft R-8TB Vertical Antenna Tilt Base last week. I was told I'd have to purchase a ROHN type tower instead and use guidelines.
So I should send back the Cushcraft vertical antenna, and plan for a ROHN? I've been watching videos on a tilt antenna. Pretty cool

Having issues with 40' antenna tower plan. I'd like to be able to lower it. I see hinge type bases on net. Are there any out there with winches? Should I use ROHN type mast, or 3" diameter mast?

Initially, I was thinking 18" of LMR400 for jumper. But now I think more like 2-3' due to the flexibility.
This is the stand for radio. I've since moved to exterior wall, to get more cable onto tower. Can I put duplexer more towards the floor, so antenna cable comes in straight and use jumper cable to attach to radios? This way would eliminate extreme bends for 1/2" Heliax, but may require longer jumper cables

Ah I missed that, thanks.
Which makes sense (in a way) since it talks about using the duplexer with two KG-1000G radios, which (of course; see my previous post) have SO-239 connectors too. There is nothing that prohibits one from having a cable with PL-259 on one end and N on the other, but those are probably much less common than jumpers with the same connectors on either end.
You're right. I'm learning as I go also. I've checked the specs for the radio and duplexer twice. I have the names in the above comments. Yes, the antenna has an N type connector. So antenna line will be PL-259 to N connector. Like wrci350 said, N connectors are waterproof. Maybe SO-239/PL-259 are more for indoor environments.

I was searching for the name, and saw it in description. MPD digital Microwave LMR400 w/ PL-259 connectors
-
So I read somewhere not to use LMR400 for anything over 300mhz. Both radio and duplexor have SO-239 connectors. I was gonna use it for jumper wire from duplexer and radio. What should I do?

Yes, the Nagoya UT-72G antenna came with a permanent 10' cable, and is in the house. The LMR-400 are jumpers from duplexer to radios. Could be the antenna, radios being too close causing desencing sounds possible too. We actually had a test yesterday. My radios and repeater were all in sync. My friend got as close to a mile from repeater, and no TX or RX. He said his radio settings have been changed. I've offered my friends to take my radios to test repeater, but no one has yet. Could WIFI box cause interference?
I went to the other band, so I could transmit like a base station. They had already turned radio off, so I couldn't test.
What if I had the repeater on, and took my HT's for a ride? That would be an acceptable test also correct?
