Can it be used to monitor Project 25 Phase I?

Hello, this is onlu an antenna kit, and it does not not include a radio. The antenna set could be used to receive P25, but you will need an appropriate radio such as an RTL-SDR to connect the antenna set to.

Seller: why are these $11.95 on your site with a button that says Buy at Amazon, but when I click it, it is $14.95 ?

Sorry the pricing on Amazon is a bit higher for some products because of their higher seller fees.

Can I hook this antenna straight to a radio?

Not a TX radio, the antenna is not designed to transmit. But to a RX only radio yes. Note that it has SMA connectors, and is designed for radios that use SMA.

I am thinking of reviewing one of these on my youtube channel (hamrad88) but would like to know how long the cables are. thanks for your time. tom

Hi Tom, the extension coax is 3 meters long, and the cable on the dipole itself is 60 cm. If you like, contact me via the blog and I can send you a free set for review on your channel.
