I'm looking to install a base station in my house. I looking at possibly using and old adjustable Directv wall mount and a few links of mast to raise a Anton 99 over the low edge of my roof line. My question is since I have a metal roof, and the peak of that roof will be higher than about 50% of the antenna will it affect reception and transmission severely?

To anyone looking to acquire commercial radio programming software:
Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.
If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.
To obtain Motorola software see the Sticky in the Motorola forum.
The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.
For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).
This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

It will probably affect it some. Do you have a vent pipe sticking out of the roof near the peak you could mount the antenna on?

The vent pipe is low on the roof also, I would gain maybe a foot more clearance at the most. I could extend the mast higher but I live on a hill and 50+ MPH wind gusts are not unusual several times a year. I even considered mounting it on my flagpole but I question of the aluminum pole can withstand the extra mass in a windstorm
How about planting a 3ft antenna tripod at the peak of the roof? You can usually measure and locate rafters or just drill holes for the tripod feet while someone is in the attic with a couple of 2X4 scraps and run lag screws into the 2X4's, sandwiching the roof.

Yes. Get the bottom of the antenna above the peak of the roof, or you will have crappy reception on the side blocked by the roof, and probably high SWR issues as well.
I would suggest a mast along the end of the house centered on the peak of the roof, concreted into the ground at the base, and attached to the eaves or side of the house near the top. That will minimize stress on the roof and minimize the possibility of causing leaks, and also help direct lightning strikes away from the house in the event of a direct hit.
