Frequently Asked Questions (FAQs)

Do I need a counterpoise with SPOOLTENNA?

We recommend using the coax shield as the return path and adding a common mode choke (if it is not built in) at the radio side of the cable to block RF from traveling back into the radio.

Better yet, our RG-316 coax with a built-in common mode choke is designed exactly for this purpose, so you don’t have to add anything extra. This is the setup we use when field testing every one of our antennas!

If you prefer to use a dedicated counterpoise wire instead of the coax shield, you can connect one at any of the SPOOLTENNA assembly screws on the front face of the unit. A simple method is to crimp a ring terminal onto your counterpoise wire and secure it under one of the assembly screws. You can also attach a ring terminal to the antenna itself and then attach the counterpoise wire on with an alligator clip.

Ensure the screw is tightened sufficiently to make proper contact with the trace on the board.

The counterpoise length should ideally be 5 to 10% of your lowest operating band. For example, if you're working on 40 meters, you should use a counterpoise length of 2 to 4 meters.

What mast do you recommend for use with SPOOLTENNA?

For our mobile-based remote operating, we use an extending painter's pole, which handles the weight of SPOOLTENNA without any issues. While we don't have a favorite commercial mast, we've heard from customers that the POTA 33 and similar heavy-duty masts work well for more substantial antennas.

Do you offer international shipping?

We are a small family business and do not have the infrastructure to manage full international shipping. We do ship to Canada and the UK, with all taxes and duties due upon arrival. Please visit our partners at DX Engineering for additional international shipping options. 

Should the feed point be high or low?

Both high and low feed point configurations are valid for SPOOLTENNA, and we describe both options in our owner's manual. You may choose the setup that works best for your specific setup. The efficiency of the antenna is nearly identical in both configurations, and there may be only slight differences in the radiation pattern. 

Do you offer a discount for veterans?

We are proud to offer a product that is designed and built in the USA, and we are forever proud and grateful for the service of our veterans. All veterans and first responders get 10% off storewide (excluding bundles which are already discounted) with the code thankyou10. 

Can I leave SPOOLTENNA up for days/weeks?

We don’t recommend it. While SPOOLTENNA is made with rugged, high-quality materials, it is designed and built for portable operating as a field antenna.

Leaving any wire antenna deployed for weeks at a time exposes it to wind and weather that can accelerate wear and shorten its service life. For best performance and longevity, we recommend deploying SPOOLTENNA when you’re operating and taking it down when you’re done.

Is SPOOLTENNA weatherproof?

SPOOLTENNA is designed to handle typical outdoor conditions you’ll encounter during portable operation, including light rain or snow and extreme temperatures (-40 to 130 degrees C). However, we recommend that you take SPOOLTENNA down during inclement weather and high winds as this can put undue stress on the wire and components.
