* NAVIGATION: To make your life easier, and help you find exactly what you want, we have broken the on-line equipment catalogs into smaller sections. Just CLICK on the item you are looking for at the left, to see the matching catalog. Large graphical catalogs are a bit SLOW, so please give them a bit of time to load. The top header of each catalog is largely the same, so don't think you are stuck in one place!

You can order anything here just by picking up the phone, and calling (250) 769-1834 during normal office hours, 8:30AM to 4:30PM PST, or FAX to (250) 769-4106. OR, Email your order to Susan CLICKHERE.

Shipping*SHIPPING: Preferred and Alternate Methods as of June 4, 2013, CLICK for FULL DETAILS ON OUR FAQ Page. Rates are now changing rapidy, often with little notice to us, so all the data has been transferred to the FAQ page for speedy updating.

* E-Mail Susan if you want a quote for shipping to other destinations, or for something heavy. Sorry, we can't safely send most individual small parts in a regular letter envelope, they get destroyed by the automated handling equipment. Sometimes we can ship very rugged parts in a small padded envelope by letter post. Ask Susan.

*There is a packing charge for large or heavy equipment, see the FAQ for details.

*If we have your valid data on file, you can just click on the ORDER email link to place an order and indicate your approval to bill, and we will do the rest. We keep your active information for ONE YEAR for your convenience.

*If this is the first time you have dealt with us, you can phone +1 (250) 769-1834 or FAX +1 (250) 769-4106 to supply the billing info, or send it by the email link, as you prefer. We accept VISA/MC, international money order, Paypal (to Susan@Okanagan.net), and bank wire transfer. Please note that there are transaction fees with Paypal and wire transfer payments, the wire transfer fee is frankly horrifying.

We accept VISA/MC or international money order

* CONDITION: To answer your questions, YES, we completely check and inspect all used equipment, and do not offer any we feel is substandard. That gear is normally scrapped, broken down for parts, or may get offered as-is in the HOT DEALS section, with the unit's condition clearly identified. If there are any marks or detracting features, we clearly state them in the listing. Before shipment, we burn in the equipment for 24 hrs. again and re-check to be sure it is good prior to shipment.

* The CATALOG will appear below shortly!
Don't forget these illustrated sections take a few seconds to load, but they are worth the wait!

Boonton high performance digital (3 1/2 digit) RF Power Meter with both dBm and uW/mW capability.
Fully overhauled, drift tested and calibrated. Available with several sensor/cable systems, see below, includes 41-4E/51013 sensor, good from 0.1Mhz to 18GHz.
Supports both linear power readings (mW/uW) and logarithmic readings in dBm, plus peaking meter. Has calibration offset for sensor correction, and low level balance adjustment. Typically 50dB-60dB of useful stable dynamic range with minimal re-zeroing, much better than many HP 43X models. Fully tested, Cable and Sensor INCLUDED!
We include a Boonton partial manual reprint with the unit.

Boonton high performance digital (3 1/2 digit) RF Power Meter with uW/mW capability.
Fully overhauled, drift tested and calibrated. Available with several OPTIONAL sensor/cable systems, see below, no sensor/cable included with this meter.
Supports both linear power readings (mW/uW) and companion peaking meter. Has calibration offset for sensor correction, and low level balance adjustment. Typically 50dB-60dB of useful stable dynamic range with minimal re-zeroing, much better than many HP 43X models. Fully tested, can be cal'd with optional sensor package for no additional charge. Note, Boonton included the Autorange and dBm positions even on units that were not equipped with these options, but they are non-functional. It is possible to upgrade these options in the field if parts are available.
We include a Boonton partial manual reprint with the unit.

Cal'd$795 ea.
Boonton high performance, high power RF Power Meter with both dBm and mW capability. A very hard to find model, this includes the sensor with built-in 10dB pad, to allow up to +20dBm (100mW) measurements, ideal for many wireless applications. The integral attenuator makes the sensor much more robust, flatter in VSWR, and harder to damage accidentally, all very useful characteristics when working at higher power levels.
Fully overhauled, drift tested and calibrated. Includes 4200-5E sensor, good from 0.1Mhz to 18GHz.
Supports both linear power readings (mW/uW) and logarithmic readings in dBm. Has calibration offset for sensor correction, and low level balance adjustment. Typically 50dB-60dB of useful stable dynamic range with minimal re-zeroing, much better than many HP 43X models, and with increased power level capability. Note that this unit has a blue rather than green faceplate, and no carry handle.Fully tested, Cable and Sensor INCLUDED!
We include a Boonton partial manual reprint with the unit.
