help with uhf antenna choice
I am looking for a cheap inexpensive 1/4 or or higher NMO mobile 70cm amateur antenna.
ANY of the advertisers, here on QRZ can sell you such an antenna.
$10 buck item or less for a 1/4-wave NMO mount mobile antenna.
Used antennas are often found in junk piles at auto body shops, junk yards, land mobile shops
Alltronics sells a 900 MHz antenna that you can use a longer whip for 70 cm
these can be found at their Santa Clara, CA store OR on eBay.
Part number: 97A005

Hi, Greg. Thank you for the reply.

At least 250 watts for most, probably more! The real limiting factor is the coax cable from the radio to the antenna. That can limit the power to around 100 to 150 watts if the cable is small enough. RG58/U can easily handle well over 100 watts.
Good. When I installed my two nmo mounts and so239 mount, I uses rg8x with double shieldeding. Foil&braid.
