Fast delivery, easy installation and economically priced.
provided as advertised , shipped quickly , came with nuts, lock washers and a gasket.
Keep up the great service.
Needed a new antenna for the GDL 82 installation, and this worked perfectly. The added stud length simplified installation through the cored-composite aircraft skin
A performer in the antenna market, easy installation and priced right.
Installed this with my KN-64 to complete my IFR capabilities. Works great. Haven’t had any issues.
Very good quality. I kept breaking the “TED” type bc of the antenna location when I would pull the cowl pins on my RV-7. I decided on the blade type since it is more durable.
Easy as pie! Good job
