Especially for cottages, you want a cheap CB base station antenna that won’t be tempting to steal. This implies a simple mobile antenna repurposed for base station use.
Note: be sure you’re well away from power lines. Do this on the opposite side of the house/cottage/shed far away from power lines.
A mobile antenna near the roof peak using half a mirror mount can screw into the metal eaves for groundplane. Height above average terrain is the most important factor in CB base station range. Depending on favorable terrain, base-base comms range on CB is over 30 miles, legally. With beam antennas and rule bending base-base CB range can be over 50 miles in quiet conditions.
You can’t just slap a mobile antenna on the roof, because it will blow over. It will have nothing to adhere magnetically to. Instead, take a mirror mount with lags drilled into the eaves with a 102” whip at the roof peak. This gives better than 1.2:1 SWR across the 40 CB channels and isn’t terribly conspicuous as to “hey there’s expensive CB stuff inside!” In fact unless you’re really looking you don’t notice it at all!
Why cottage CB radio?
A CB radio in your cattage gives a heads up when a group is coming back from town or an adventure at one of the lakes–we should get a good 30 minutes’ driving time range base-mobile assuming SSB CB radio. This gives some peace of mind in case of a breakdown–not that anyone listens to channel 9, but that home base or another base station can be reached on the local channel. These roads are highly isolated and you just never know what you’d run into on a breakdown.
