Antennas for portable equipment presented below:
The first antenna presented is from Jetfon a 2m / 70 cm dual-band handheld radio antenna led stubby Tx, the price is 15 EUR, technical specifications here:
Code | Type | Length | Weight | Power rating | Connector | Colour |
DB-110 M/F | 1/4 λ | <= 11.5 cm. | <= 11 gr. | 10 W | SMA M / F | Red (M) / Green (F) |
The next antenna I have tested and used on a daily basis is from D-ORIGINAL, dual-band 70 CM and 2 m lambda, price expected 10 EUR, specs below:
Code | Type | Length | Weight | Power rating | Connector | Colour |
DX-DB-45-LED-M/F | 1/6 λ? | 40 mm. | < 10 gr. | 10 W | SMA M / F | Black with red LED light |
One of the antennas which are my daily driver in terms of performance is Nagoya NA-701, dual-band 70 CM and 2 m lambda, price expected 20 EUR, technical specs below:
Code | Type | Length | Weight | Power rating | Connector | Impedance |
NA-701 | 1/4 λ | 17 cm. | < 25 gr. | 10 W | SMA M, F or BNC | 50 Ω |
Besides a good performance in the field for transmission (acceptable SWR) offers wide receiving coverage 120 / 150 / 300 / 450 / 900 MHz.
One of the radials I am using is from Komunica which is performing well, a couple of tech details:
Code | Gain | Type | Impedance | Power rating | Connector |
PWR-SRH-519 | 3 dBi | 1/4 λ | 50 Ω | 10 W | SMA |
A mini dual-band antenna (144/430 Mhz) with extended receive coverage (150/300/450/800Mhz) weighs just 9 grams and 21 cm length.
